Ingredients You Need

• 2 tablespoons unsalted butter (use olive oil if dairy-free)
• 1 medium yellow onion, finely chopped
• 3 garlic cloves, minced
• 1/4 cup all-purpose flour (use gluten-free flour blend to make GF)
• 4 cups low-sodium chicken or vegetable broth (brand note: Swanson or Pacific work well)
• 2 cups whole milk or half-and-half (substitute oat milk for dairy-free, expect slightly thinner texture)
• 8 ounces sharp cheddar, shredded (Cabot or Tillamook shred best; avoid pre-shredded cheese if you can because anti-caking agents reduce melt)
• 1 cup grated Parmesan or Romano (optional, adds nutty depth)
• 10 ounces lasagna noodles, broken into 1-2 inch pieces (use no-boil lasagna sheets or short pasta like rotini as a shortcut)
• 3 cups broccoli florets, chopped into bite-size pieces (frozen broccoli works; add a minute or two extra simmer)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1/4 teaspoon red pepper flakes (optional, add a gentle kick)
• 1/2 cup heavy cream (optional for extra richness)
• Fresh parsley or basil, chopped, for garnish

Pantry shortcuts and substitutions inline: use frozen broccoli, pre-chopped onion mixes, or leftover cooked pasta for quicker assembly. Swap cheddar for Colby or Monterey Jack if you want milder cheese. For vegetarian version use vegetable broth.

Equipment

• Large heavy-bottomed pot or Dutch oven
• Wooden spoon or silicone spatula
• Whisk
• Chef knife and cutting board
• Grater (unless you use pre-shredded cheese)
• Ladle and bowls for serving

How to Make Broccoli Cheddar Lasagna Soup Recipe

Prep (10 minutes)

Chop the onion, mince the garlic, and break the lasagna noodles into bite-size pieces. Shred the cheddar and grate the Parmesan if you use it. Cut the broccoli into small florets so they cook evenly.

Make the soup base (10 minutes)

Heat the pot over medium heat and melt the butter. Add the onion, and sauté until translucent, about 4 minutes. Add the garlic and cook 30 seconds until fragrant.

Thicken and add liquids (5 minutes)

Sprinkle the flour over the onions and stir well to coat; cook the flour for 1 to 2 minutes while stirring to remove the raw taste. Slowly whisk in the broth and then the milk so the mixture stays smooth. Bring the pot to a gentle simmer.

Cook noodles and broccoli (8-10 minutes)

Add the broken lasagna pieces to the simmering soup and stir frequently to prevent sticking. After the noodles cook about 4 minutes, add the broccoli florets so they stay bright and slightly crisp. Simmer until the noodles and broccoli reach your desired tenderness.

Finish with cheese and seasoning (2-3 minutes)

Lower the heat and stir in the shredded cheddar and grated Parmesan off direct heat so the cheese melts smoothly. Add the heavy cream if you want a richer texture. Taste and season with salt, pepper, and red pepper flakes.

Tips & Common Mistakes

• Use freshly shredded cheddar for the best melt; pre-shredded often yields a grainy texture.
• Cook the flour briefly before adding liquid to avoid a raw flour taste.
• Add broccoli late so it stays vibrant and does not turn mushy.
• Keep heat low when adding cheese to prevent separation.
• If the soup becomes too thick after chilling, whisk in a splash of broth or milk while reheating.
• Avoid overcooking the noodles; they continue to soften in the hot soup after you remove the pot from heat.

Variations I've Tried

• Chicken boost: I shred a rotisserie chicken into the soup for extra protein and weeknight ease. It adds depth without extra cooking time.
• Veggie-forward: I swapped half the noodles for diced potatoes and added extra broccoli for a heartier, more vegetable-forward bowl.
• Spicy cheddar: I mixed in pepper jack with the cheddar for a peppery twist that kids tolerated once they saw the cheese.
• Gluten-free: I used gluten-free lasagna sheets and a gluten-free flour blend to make the roux; it worked well with slightly longer noodle cooks.

How to Serve

Serve this soup with crusty bread or garlic breadsticks to soak up the cheese and broth. Offer a simple green salad or roasted vegetables on the side to balance the richness. Top each bowl with extra shredded cheddar and a sprinkle of fresh parsley for color and brightness. Keep the portion sizes generous; this soup fills bowls and stomachs fast.

Make-Ahead and Storage

Cool the soup to room temperature before storing to preserve texture and flavor. Store in airtight containers in the fridge for up to 4 days. Freeze in meal-sized portions for up to 3 months; thaw overnight in the fridge before reheating. Reheat gently on the stove over low heat and stir in a splash of broth or milk to revive the texture and keep the cheese smooth.
