25 Simple White Lasagna Soup for Busy Weeknights

White lasagna soup takes everything you love about a baked white lasagna — tender pasta, a rich cream sauce, melted mozzarella and a dollop of ricotta — and turns it into a spoonable one-pot meal in under an hour. Instead of layering and baking, you simmer broken lasagna sheets straight in a garlicky chicken and cream broth, so there's no assembly and only one pot to wash up. It's warming, filling and endlessly adaptable, whether you want it meat-free, extra cheesy, or on the table in 30 minutes flat. Below are 25 variations, plus a tested base recipe, pro tips and storage advice to get you started.

This is the benchmark version: cubed chicken breast simmered in a butter-and-flour roux base with chicken stock, half-and-half, baby spinach and torn lasagna sheets. Mozzarella and Parmesan melt straight into the broth for body, while a spoonful of ricotta swirled into each bowl at the table adds that classic lasagna tang. Cook the noodles directly in the soup for the last 10-12 minutes so they soak up the garlicky broth rather than boiling them separately. Use chicken thighs instead of breast if you want a richer, slightly more forgiving result.

Skip cooking raw chicken altogether and stir in about 300 g (2 cups) of shredded rotisserie chicken once the broth and cream base is simmering, so it just needs to heat through. This shaves roughly 10 minutes off the recipe and adds a deeper, roasted flavour that plain poached chicken doesn't have. Add the chicken at the same time as the noodles so nothing overcooks or dries out. It's the version to reach for on a night when you genuinely don't want to touch raw meat.

Swap the chicken for 450 g (1 lb) mild or hot Italian sausage, squeezed from its casing and browned in the pot until crumbly and no longer pink, with an internal temperature of at least 71°C (160°F), before you build the roux. The rendered fat replaces some of the butter and gives the broth a deeper, savoury backbone that pairs especially well with extra Parmesan. Drain off any excess fat before adding the flour so the roux doesn't turn greasy or split. This is the heartiest, most filling variation in the lineup, ideal for cold-weather dinners.

A pinch of freshly grated nutmeg, about ¼ teaspoon, stirred into the roux alongside the half-and-half gives this version the same warm, cosy note found in classic béchamel-based lasagnas. Use full-fat cream instead of half-and-half for extra silkiness, and let the soup rest off the heat for 5 minutes before serving so the flavours settle. A final scatter of chopped fresh parsley brightens the richness. It's the version to make when you want something that genuinely tastes like a hug.

Replace the ricotta topping with 60 g (¼ cup) of mascarpone stirred directly into the hot broth just before serving for an ultra-silky, almost velvety texture. Mascarpone melts more smoothly than ricotta and won't turn grainy, so it's a good option when you're serving guests. Keep the heat low once it's added, since mascarpone can split if the soup is boiling hard. This is the richest, most indulgent version in the whole lineup.

Strip the recipe back to chicken stock, a jar of Alfredo sauce, shredded rotisserie chicken, broken lasagna sheets and a bag of pre-shredded Italian cheese blend. Simmer the stock and Alfredo sauce together, cook the noodles in it for 10-12 minutes, then stir in the chicken and cheese until melted. It won't taste quite as layered as the classic version, but it's on the table in about 20 minutes with almost no chopping. Good for beginner cooks or genuinely rushed weeknights.

Build the cheese element from four types — mozzarella, Parmesan, provolone and a little cream cheese whisked in at the end — for a broth that clings thickly to the noodles. Add the cream cheese in small cubes off the heat, stirring until fully melted, so it doesn't clump. This version is noticeably thicker than the classic, closer to a chowder than a broth-forward soup. Finish with extra mozzarella on top and a few seconds under the grill if your bowls are oven-safe.

Add a bay leaf and two sprigs of fresh thyme to the broth and let it simmer gently for 25-30 minutes before adding the noodles, so the stock reduces slightly and the flavours deepen. This longer simmer is what separates a good white lasagna soup from a great one; rushing the base stage means a thinner, flatter-tasting broth. Fish out the bay leaf and thyme stems before serving. Best made on a lazy Sunday when you're not watching the clock.

Use a stock cube dissolved in water instead of fresh stock, frozen chopped spinach, thawed and squeezed dry, instead of fresh, and the broken ends of a box of dried lasagna sheets that would otherwise go to waste. Pre-shredded supermarket cheese blend works fine here too since it's melting into a broth rather than being baked. None of these swaps noticeably change the finished flavour. This is the version to make when you're cooking from what's already in the cupboard.

Use pre-diced onion, jarred minced garlic and rotisserie chicken to cut prep to almost nothing, and simmer everything together while the noodles cook directly in the pot. The whole soup, start to finish, fits inside 30 minutes if your stock is already hot when you add it. Keep the noodle pieces small, snapping sheets into 3-4 cm lengths, so they cook faster and more evenly. Set a timer specifically for the noodles, since overcooking is the main risk when you're moving quickly.

Sauté 200 g (7 oz) sliced cremini mushrooms in the butter until deeply golden before you build the roux, then continue with the recipe as usual. The mushrooms add an earthy, umami depth that works especially well alongside the chicken, and their released liquid enriches the broth naturally. Don't crowd the pan when browning them or they'll steam instead of caramelising. A handful of chopped chives on top finishes it nicely.

Combine 225 g (8 oz) crumbled Italian sausage with 4 rashers of chopped smoky bacon, browning both together until the sausage is no longer pink and reaches an internal temperature of at least 71°C (160°F), before starting the roux. Reserve a spoonful of the crispy bits to scatter over each bowl at serving for texture and smoky flavour throughout. This is the most indulgent, protein-heavy version of the soup, so it easily stretches to 8 servings instead of 6. Pair it with a simple green salad to balance the richness.

Drop the black pepper and any chilli flakes, use mild Italian sausage or plain chicken, and stir the spinach in very finely chopped so younger eaters barely notice it. Add an extra 60 g (½ cup) of noodles since kids tend to prefer a soup that's more pasta than broth. Serve with extra mozzarella on the side so everyone can customise their own bowl. This version keeps flavours gentle without losing the comforting cheese-and-cream base.

Ladle the finished soup into oven-safe bowls, top generously with mozzarella and a little extra Parmesan, then grill (broil) for 2-3 minutes until bubbling and golden brown in spots, just like a lasagna fresh from the oven. Watch it closely under the grill since cheese can go from golden to burnt in under a minute. This step turns a good soup into a genuine showstopper for guests. Serve immediately while the cheese top is still molten.

Every element — searing the chicken, building the roux, simmering the broth and cooking the noodles — happens in a single large pot or Dutch oven, so there's no extra pan for the roux and no colander for draining pasta. This keeps washing-up to one pot and a wooden spoon. Use a heavy-based pot at least 5 litres (5 quarts) so there's room for the noodles to cook without the soup boiling over. It's the most practical version for a busy weeknight kitchen.

Brown the chicken or sausage and make the roux on the stovetop first, then transfer everything except the noodles, cream and cheese to a slow cooker and cook on low for 4-5 hours. Stir in the broken noodles, cream and cheeses during the final 20-30 minutes of cooking so they don't turn to mush over the long simmer. This is the version to start before you leave for work. Add the spinach right at the end so it wilts rather than overcooks.

Sauté the chicken, onion and garlic using the pot's sauté function, then pressure cook the stock and seasonings for 8 minutes on high with a quick release. Stir in the broken noodles and simmer using the sauté function for 8-10 minutes until tender, then finish with cream, spinach and cheese off the heat. This cuts the hands-off cooking time significantly compared with the stovetop method. Avoid pressure cooking the noodles themselves, since they turn gluey under pressure.

Use gluten-free lasagna sheets or gluten-free penne in place of regular pasta, and swap the plain flour in the roux for the same amount of cornflour (cornstarch) mixed with a little cold stock before whisking in. Gluten-free pasta can turn mushy faster than regular wheat pasta, so check it a couple of minutes earlier than the recipe states. Double-check your stock and cheese are labelled gluten-free, since some brands add wheat-based thickeners. Otherwise the method is identical to the classic version.

Replace the butter with olive oil, the half-and-half with full-fat oat or cashew cream, and use a dairy-free mozzarella-style shred plus nutritional yeast in place of Parmesan for a cheesy, savoury note. Skip the ricotta topping or use a dairy-free ricotta alternative if you can find one locally. The broth will be slightly thinner than the dairy version, so let it simmer a few extra minutes to reduce and concentrate the flavour. It still delivers the same comforting, creamy character.

Leave out the chicken or sausage entirely and bulk the soup up with 200 g (7 oz) sliced mushrooms and a drained 400 g (14 oz) tin of cannellini beans for protein and texture. Use vegetable stock instead of chicken stock, and add the mushrooms early so they have time to brown and release their liquid into the broth. Everything else, including the roux, spinach, cheese and ricotta finish, stays the same. It's just as filling as the meat versions thanks to the beans and pasta.

Swap the lasagna sheets for cauliflower florets cut into small pieces, added in the last 8-10 minutes of simmering until just tender, and reduce the flour in the roux to 1 tablespoon, thickened instead with an extra splash of cream. The result won't be identical to the pasta version, but it keeps the same garlicky, cheesy broth and chicken. Chicken thighs work particularly well here since they stay juicy over the slightly longer simmer the cauliflower needs. Skip the ricotta topping if you're watching carbs closely, since a small amount still adds up.

Stir 1-2 tablespoons of chopped Calabrian chillies, or ½ teaspoon of crushed red pepper flakes, into the butter before adding the flour, so the heat infuses the entire roux rather than sitting on top. The chilli's fruity heat cuts nicely through the richness of the cream and cheese. Taste and adjust before adding more, since Calabrian chillies vary in strength between jars. A scattering of fresh basil at the end balances the spice with a cooling, herby note.

Cut the noodles into very short pieces, about 2 cm, before cooking so they're easy for small mouths to eat with a spoon, and blitz the spinach with a splash of stock before adding it so it disappears into the broth. Keep seasoning mild and let everyone add their own extra cheese at the table. This version leans even further into ease of eating for younger children than the family-friendly one. It freezes well in small portions for easy weeknight reheats too.

Cook the broth, chicken, cream and cheese base fully, but keep the noodles in a separate container and combine only when reheating each portion, since noodles left sitting in the broth for days over-absorb liquid and turn soft. Portion into 4-6 airtight containers and refrigerate for up to 4 days. Reheat gently on the stovetop or in the microwave, adding a splash of stock or milk to loosen the broth if it's thickened too much in the fridge. This keeps every portion tasting freshly made.

Make the soup through the cream-and-cheese stage but leave out the noodles entirely, then cool and freeze in an airtight container for up to 3 months. Thaw overnight in the fridge, reheat gently on the stovetop, and cook fresh noodles directly in the reheated broth for 10-12 minutes just before serving. Freezing with the noodles already in results in a mushy, waterlogged texture once thawed, so this two-stage method is worth the small extra effort. Label the container with the date so you know how long it's been in the freezer.

Toast the flour in the melted butter for a full minute before adding any liquid; this cooks out the raw flour taste and prevents a pasty texture in the finished broth. Add the noodles directly to the simmering soup rather than boiling them separately, since they release starch that naturally thickens the broth as they cook. If the soup turns out thicker than you'd like, thin it with a splash of warm stock or milk rather than water so you don't dilute the flavour. Always taste and adjust salt at the very end, since both Parmesan and stock add their own sodium.

Ladle the soup into deep bowls and top each portion with a generous spoonful of ricotta, a crack of black pepper and a few torn basil leaves. Warm, crusty garlic bread or a simple green salad with a sharp vinaigrette balances the richness of the broth perfectly. For a heartier meal, serve alongside garlic knots or a side of roasted vegetables. A glass of crisp white wine, such as Pinot Grigio, complements the creamy, cheesy flavours well.

Store leftovers in an airtight container in the fridge for up to 3 days; the noodles will keep absorbing broth as they sit, so expect a thicker soup by day two. Reheat gently on the stovetop over medium-low heat, stirring in a splash of stock or milk (rather than water, which dilutes the flavour) to loosen it back to a pourable consistency. Avoid boiling it hard when reheating, as this can cause the cream sauce to split. For longer storage, freeze the base without noodles for up to 3 months and cook fresh noodles in it when you're ready to serve.
