30-Minute Lasagna Soup

Lisa Anderson

Lasagna soup delivers all the familiar flavors of classic lasagna—seasoned ground meat, tomato broth, herbs, ricotta, and melted mozzarella—in a single pot on the stovetop. Breaking lasagna noodles directly into the simmering broth cuts out the baking step entirely, so the whole meal comes together in about 30 minutes.

Equipment

Large heavy-bottomed pot or Dutch oven (5–6 quart)
Chefs Knife
Cutting board
Wooden spoon or silicone spatula
Measuring cups and spoons
Small mixing bowl (for ricotta topping)
Ladle
Microplane or fine grater (for lemon zest and Parmesan)

Ingredients

For the Lasagna Soup Base:

2 tablespoons extra-virgin olive oil use a fruity, peppery oil for best aroma
12 ounces Italian sausage, casings removed mild or hot; high-quality pork sausage develops better fond
1 medium yellow onion, finely diced about 1 cup when diced; choose firm, heavy onions
4 cloves garlic, minced freshly minced for fullest flavor; avoid jarred if possible
2 tablespoons tomato paste double-concentrated preferred for deeper caramelization
28 ounces crushed tomatoes 1 can; San Marzano-style recommended (e.g., Mutti or Cento)
5 cups low-sodium chicken broth or vegetable broth for vegetarian version; low-sodium lets you season precisely
8 ounces lasagna noodles, broken into 2-inch pieces standard or no-boil; stir well to prevent sticking
1 teaspoon dried oregano rub between fingers to awaken oils
1 teaspoon dried basil or 1 tablespoon finely chopped fresh at the end for brightness
0.5 teaspoon red pepper flakes adjust to taste for gentle heat (optional)
1.25 teaspoons kosher salt divided, plus more to taste; brands vary in salinity
0.5 teaspoon freshly ground black pepper divided; grind fresh for best aroma
1 teaspoon balsamic vinegar balances acidity and rounds flavors at the end (optional but recommended)

For the Herbed Ricotta & Finishes:

1 cup whole-milk ricotta look for a creamy, full-fat ricotta; Calabro or BelGioioso are reliable brands
0.5 cup freshly grated Parmesan cheese grate from a wedge for best melt and flavor; plus extra for serving
1 cup shredded low-moisture mozzarella for that signature lasagna stretch on top
0.25 cup fresh basil leaves, finely chopped reserve some small leaves for garnish; fresh basil adds a verdant aroma
1 teaspoon lemon zest microplaned; brightens the ricotta with subtle citrus lift (optional)
1 tablespoon extra-virgin olive oil, for finishing a light drizzle before serving adds sheen and aroma (optional)

Instructions

Prep (10 minutes): Finely dice the onion, mince the garlic, and measure spices. In a small bowl, mix ricotta, Parmesan, lemon zest, half the basil, and a pinch of black pepper until creamy; set aside. This herbed ricotta will be dolloped over the hot soup.
Brown the Sausage (about 4 minutes): Heat a large pot over medium-high heat (about 400°F / 200°C). Add the olive oil, then the Italian sausage. Cook, breaking it into crumbles, until well browned with crisp edges. Browning develops fond—those caramelized bits that deepen flavor.
Soften Aromatics (about 3 minutes): Add the onion and 1/2 teaspoon kosher salt. Sauté on medium-high until translucent and sweet, stirring to lift fond. Add the garlic and cook 30 seconds until fragrant—avoid browning.
Caramelize Tomato Paste (1 minute): Stir in the tomato paste and cook, stirring, until it turns a deeper brick red and smells jammy. This quick caramelization adds umami and body.
Build the Broth (2 minutes to come to a boil): Add the crushed tomatoes, chicken broth, oregano, dried basil, remaining salt, black pepper, and red pepper flakes. Stir and bring to a lively simmer over medium-high heat (185–203°F / 85–95°C).
Cook the Noodles (8–10 minutes): Add the broken lasagna noodles. Reduce heat to maintain a steady simmer (around 190°F / 88°C). Cook, stirring frequently so the pieces don't clump or stick to the bottom, until al dente. If the soup thickens too much, splash in hot water a little at a time to reach a stew-like consistency.
Finish and Balance (about 1 minute): Off the heat, stir in the balsamic vinegar and remaining basil. Taste and adjust salt and pepper. The broth should taste savory, bright, and gently spicy.
Serve: Ladle into warm bowls. Dollop with the herbed ricotta, sprinkle generously with mozzarella and extra Parmesan, and finish with a few basil leaves and a glossy drizzle of olive oil. The mozzarella should soften and string as it meets the heat.

Notes

Lisa’s Tips:

Flavor Boost: Brown the sausage well—color equals flavor. If the pot looks dry, add another teaspoon of olive oil to keep fond from scorching.
Ricotta Texture: For ultra-smooth dollops, whisk in 1–2 tablespoons warm broth to the ricotta mixture right before serving.
Noodle Control: Break noodles unevenly for a rustic, spoonable “lasagna” experience. Stir often in the first few minutes to avoid sticking.
Substitutions: Use ground turkey + 1 teaspoon fennel seeds for a lighter take; or make it vegetarian with plant-based Italian sausage or sautéed mushrooms and vegetable broth.
Gluten-Free: Swap in gluten-free lasagna noodles and stir gently—they can be more delicate.
Dairy-Free: Use a dairy-free ricotta and mozzarella alternative; finish with extra-virgin olive oil and nutritional yeast for a savory lift.
Herb Swap: Stir in a handful of chopped fresh spinach or kale during the last 2 minutes for extra color and nutrition.
Make-Ahead: Broth and sausage base can be made 2 days ahead; cook noodles to order in the reheated broth to avoid sogginess.

Serving Suggestions:

Warm shallow bowls showcase the vibrant red broth against creamy white ricotta and the green pop of basil. Finish with a fine rain of Parmesan and a light olive oil sheen. Pair with a simple arugula salad dressed in lemon and a slice of toasted garlic bread. A medium-bodied Italian red (Sangiovese) or a sparkling water with lemon complements the richness.

Culinary Context:

While classic lasagna is layered and baked, Italian home cooks have long transformed pantry staples into hearty soups. This bowl borrows the soul of lasagna—tomato, pasta, cheese, and sausage—and channels it into a faster, weeknight form without sacrificing depth.

Optional Advanced Instructions:

Stock Shortcut: Simmer the broth with a Parmesan rind while you prep; remove before adding noodles for an extra-savory backbone.
Parallel Cooking: Start browning sausage as you dice the onion to shave minutes without compromising flavor—just keep an eye on the heat.
No Mortar and Pestle? If using whole fennel or peppercorns, crush lightly with the bottom of a pan or use a spice grinder for a coarser, rustic texture.
