Ingredients Breakdown

Let’s take a closer look at what makes this soup so satisfying:

Savory Base:

  Adds richness and flavor—use Italian sausage for extra spice or mild for a kid-friendly version.
• Onion (1 small, chopped)
  Adds sweetness and depth.
• Mushrooms (8 oz, sliced)
  Add umami and texture—white or cremini both work well.
• Garlic (2 cloves, minced)
  Adds aromatic punch and savory warmth.

Optional: Use ground turkey or plant-based sausage for variation.

Vegetables & Broth:

• Baby spinach (4 cups)
  Adds color, nutrients, and freshness—stirred in at the end for best texture.
• Chicken broth (5 cups, low sodium)
  Forms the soup base—adjust salt to taste depending on broth.

Tip: Use vegetable broth for a vegetarian version.

Pasta & Herbs:

• Lasagna noodles (5, broken)
  Adds classic lasagna texture—break into bite-sized pieces before cooking.
• Dried oregano (1 tsp)
  Adds herbal depth.
• Dried basil (½ tsp)
  Adds sweetness and aroma.

Optional: Add red pepper flakes or thyme for extra flavor.

Alfredo Sauce:

• Butter (3 tbsp)
  Forms the roux base—adds richness.
• Flour (3 tbsp)
  Thickens the sauce—whisk well to avoid lumps.
• Milk (1 cup)
  Adds creaminess—use whole milk for best texture.
• Parmesan cheese (1 cup, grated)
  Adds salty, nutty flavor—melted into the sauce for a silky finish.

Optional: Add cream cheese or heavy cream for extra indulgence.

Step-by-Step Instructions

Step 1: Brown the Sausage

In a large saucepan over medium heat:

• Cook ground sausage until browned, breaking it up with a spoon.

Add chopped onion and sliced mushrooms.

Cook for 5–6 minutes over medium-low heat, until vegetables are softened.

Tip: Drain excess fat if needed for a lighter soup.

Step 2: Add Garlic and Spinach

Stir in minced garlic and baby spinach.

Cook for 1 minute, stirring until spinach begins to wilt.

Optional: Add garlic earlier for a deeper flavor.

Step 3: Add Broth and Simmer

Pour in chicken broth.

Simmer for 5 minutes to meld flavors.

Tip: Taste and adjust seasoning before adding noodles.

Step 4: Add Pasta and Herbs

Add broken lasagna noodles, oregano, and basil.

Bring to a low boil.

Cook for 10–12 minutes, until noodles are tender.

Stir occasionally to prevent sticking.

Optional: Add more broth if soup thickens too much.

Step 5: Make the Alfredo Sauce

In a separate skillet over medium-low heat:

• Melt butter and whisk in flour.

Cook for 1 minute, whisking constantly until bubbling.

Slowly whisk in milk.

Continue whisking for 3–5 minutes, until smooth and thickened.

Turn off heat and whisk in grated Parmesan.

If cheese doesn’t melt, return to very low heat and whisk until creamy.

Tip: Use freshly grated Parmesan for best melting and flavor.

Step 6: Combine and Serve

Slowly whisk Alfredo sauce into the soup mixture.

Stir until fully combined and creamy.

Let simmer for 2–3 minutes to thicken slightly.

Ladle into bowls and serve hot.
