This Instant Pot lasagna soup has been a life-saver on busy weeknights and quickly became one of my go-to family meals the first time I tested it. I’m Justine, and I fell in love with this version because it takes the layered flavors of lasagna—rich meat, tangy tomato, and melty cheese—and compresses them into a single pot. I discovered the combination on a frantic week when pantry ingredients and a single jar of sauce needed to stretch into something comforting; the pressure cooker turned simple staples into something that tasted like it had been simmering all afternoon. The result is bold, saucy, and perfectly balanced: tender pasta, savory meat, and bright tomato notes finished with creamy ricotta and stretchy mozzarella. What makes this version special is how forgiving it is. Using a jar of good-quality spaghetti sauce (I like Rao’s or a local organic brand) plus canned diced tomatoes and broth creates depth without fuss. The texture is what sells it: the noodles cook to just-tender in the pressure environment and soak up the savory broth without turning to mush when you follow the quick-release timing. I often double it for meal prep or halve it for a smaller household. Picky eaters love scooping the cheesy spoonfuls, and guests often assume I spent much longer in the kitchen than I actually did.

Ingredients

• Ground beef (1 pound): I prefer 80/20 for body and flavor; if you like leaner, use 93/7 but add a teaspoon of olive oil when browning. For a spicier bowl, try spicy ground sausage (Jimmy Dean spicy is a nostalgic favorite here).
• Onion (1/2 medium, diced): Yellow onion gives sweetness when sautéed; dice small so it softens quickly in the sauté step and dissolves into the broth.
• Diced tomatoes (1 cup, canned): Use a good-quality canned diced tomato (with juices) for texture and acidity—San Marzano style or Muir Glen if you like a brighter tomato note.
• Beef broth (40 fl oz): You can substitute chicken broth for a lighter flavor; use low-sodium if you’re watching salt because jarred sauce adds sodium too.
• Spaghetti sauce (1 jar, 24 oz): A high-quality jarred sauce speeds things up—choose one with herbal notes (basil, oregano) for authentic flavor. Rao’s, Prego Farmers’ Market, or a local brand all work well.
• Uncooked pasta (1.5–2 cups): Broken lasagna, bowtie, or small shells all work; measure by volume—about 1.5 cups for a firmer texture, 2 cups if you like it saucier. Don’t over-stir after adding or it may foam.
• Salt and oregano (pinch each): Small adjustments after tasting will bring the bowl together; oregano enhances the Italian profile without overpowering.
• Mozzarella (1 cup, shredded): For topping—use whole-milk mozzarella for the best melt and stretch.
• Ricotta (1 cup, optional): Spoon on top for creaminess; the soup is delicious without it, but ricotta adds that classic lasagna creaminess in each bite.

Instructions

Set up the cooker: Attach and heat the pressure cooker on the sauté setting. Add a drizzle of olive oil (about 1 tablespoon) and let it shimmer so it coats the base—this prevents the meat from sticking and gives a gentle fond for flavor. Brown the meat and soften the onion: Add the ground beef (1 pound) and diced onion (1/2 medium) to the pot. Use a wooden spoon to break the meat into small pieces and cook until no pink remains, about 4–6 minutes. Scrape the bottom to lift any browned bits—those are flavor nuclei for the broth. Press CANCEL when done. Add liquids and seasonings: Pour in the canned diced tomatoes (1 cup with juices), beef broth (40 fl oz), and the jar of spaghetti sauce (24 oz). Sprinkle a pinch of salt and oregano. Stir briefly to combine, scraping any remaining stuck bits. The goal is an even base for the pasta to cook in. Layer the pasta: Scatter the uncooked pasta (1.5–2 cups) evenly over the top and gently press it into the liquid so it’s submerged but don’t stir. This prevents foaming and sticking to the pot’s heating element and helps the pasta cook evenly under pressure. Pressure cook: Seal the lid and set to high pressure for 3 minutes. If your cooker uses a manual or pressure button, choose high. It takes a few minutes to come to pressure—this extra time helps hydrate the pasta without overcooking. Quick release and finish: Perform a quick release as soon as the 3 minutes are up; carefully unlock and remove the lid. Give the soup a gentle stir to break up any clumped pasta. Spoon dollops of ricotta and sprinkle shredded mozzarella over each serving so the cheeses gently melt into the hot soup.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 4 days. Because the pasta continues to absorb liquid, add 1/4 to 1/2 cup of broth or water when reheating to restore a soupier consistency. For freezing, cool completely and portion into freezer-safe containers, leaving headspace for expansion; freeze up to 3 months. Thaw in the refrigerator overnight and reheat gently on the stovetop over low heat, stirring frequently to reincorporate any separated fats. Add fresh mozzarella or ricotta when serving to revive the creamy texture.

Ingredient Substitutions

If you want to lighten the bowl, swap ground beef for ground turkey or chicken and use part-skim mozzarella. For a bolder profile, use Italian sausage (mild or spicy) or a blend of beef and sausage. Gluten-free pasta can replace standard pasta—start with 1.5 cups and reduce cook time slightly because some gluten-free shapes soften faster. If you prefer a thicker finish, use 32 ounces of sauce and reduce broth to 32 fl oz. You can also stir in a handful of spinach at the end for added color and nutrients.

Serving Suggestions

Serve with crusty garlic bread or a simple green salad dressed in lemon vinaigrette to cut through the richness. Garnish bowls with fresh basil, a drizzle of extra-virgin olive oil, and grated Parmesan for extra umami. For a family-style meal, set out bowls of shredded mozzarella and ricotta so everyone customizes their portion. This soup pairs well with a light red wine such as Chianti or with sparkling water and lemon for a non-alcoholic option.

Cultural Background

This pot of saucy pasta borrows its DNA from classic Italian lasagna but is firmly rooted in Italian-American home cooking—where convenience meets tradition. The idea of transforming layered casseroles into one-pot meals grew from busy households wanting the comforting lasagna flavors without the long bake time. Pressure cooking accelerates the melding of flavors, echoing the slow-simmered sauces of Italy but with modern kitchen efficiency. Variations around the U.S. reflect local tastes, from spicy sausage versions to veggie-forward takes with mushrooms and zucchini.

Seasonal Adaptations

In summer, brighten the bowl by adding fresh chopped tomatoes and basil after cooking instead of canned tomatoes, and reduce sauce slightly to keep it fresh. In colder months, use a heartier meat blend and add a splash of red wine to the sauce before pressure cooking for depth. For holiday gatherings, add roasted garlic and a sprinkle of toasted pine nuts on top for an unexpected festive touch.

Meal Prep Tips

Make a double batch and portion into 2–3 cup containers for easy lunches—leave out ricotta and mozzarella and add fresh when reheating. To speed evening assembly, brown the meat and refrigerate the base (meat + sauce + broth) for up to 24 hours and finish in the Instant Pot when ready. Use freezer-safe single portions for grab-and-go dinners; defrost overnight for best texture.

Enjoy the simplicity of a cozy, lasagna-flavored bowl that’s fast enough for weeknights but comforting enough for company. Treat it as a template—swap proteins, alter the cheese, and make it your own.
