Instead of the traditional tomato sauce, this soup features a velvety white sauce made with butter, cream, and Parmesan, delivering a decadent flavor profile. It’s a perfect comfort food for chilly days, offering the heartiness of lasagna in a quicker, easier-to-make format. The soup typically includes broken lasagna noodles, Italian sausage or ground beef, spinach or kale for a touch of green, and plenty of cheese for that signature lasagna vibe.

This dish is ideal for those who love creamy soups and want a fun twist on traditional lasagna. It’s versatile, allowing for substitutions like chicken, veggies, or even gluten-free noodles to suit various dietary needs. Best of all, it’s a one-pot wonder, minimizing cleanup while maximizing flavor.

How to Make Creamy Alfredo Lasagna Soup

Follow these simple, step-by-step instructions to create a pot of creamy Alfredo lasagna soup that’s bursting with flavor. Each step is designed to be straightforward, with key actions bolded for clarity.

1. Cook the sausage: Heat olive oil in a large pot or Dutch oven over medium heat. Add Italian sausage, breaking it up with a wooden spoon, and cook for 5-7 minutes until browned. Remove excess fat if desired.
2. Sauté the aromatics: In the same pot, add diced onion and sauté for 3-4 minutes until softened. Add minced garlic and sauté for 30 seconds until fragrant.
3. Add broth and noodles: Pour in the chicken broth and stir in the broken lasagna noodles and Italian seasoning. Bring to a boil, then reduce to a simmer. Cook for 10-12 minutes until the noodles are al dente.
4. Incorporate the Alfredo sauce: Stir in the Alfredo sauce and heavy cream, mixing until well combined. Simmer for 3-5 minutes to meld the flavors.
5. Add greens and cheese: Stir in the spinach or kale and cook for 1-2 minutes until wilted. Add Parmesan cheese and stir until melted. Taste and adjust seasoning with salt, pepper, or red pepper flakes.
6. Serve and garnish: Ladle the soup into bowls. Dollop with ricotta cheese (if using) and sprinkle with fresh parsley and extra Parmesan. Serve warm with crusty bread!

Can You Use Jarred Alfredo Sauce in Soup?

Absolutely, you can use jarred Alfredo sauce in this soup for convenience! Store-bought Alfredo sauce is a fantastic time-saver, especially for busy weeknights. Look for high-quality brands with real cream and Parmesan for the best flavor. A 15-ounce jar typically works well for this recipe, but you can adjust the amount to taste. If the jarred sauce is too thick, thin it out with a splash of broth or cream during cooking. For a homemade touch, you can enhance jarred sauce by adding extra garlic, a pinch of nutmeg, or a sprinkle of fresh herbs. If you prefer homemade Alfredo, melt 2 tbsp butter, whisk in 1 cup heavy cream and 1 cup grated Parmesan, and season to taste—use this in place of the jarred sauce.

How to Thicken Alfredo Lasagna Soup

If your soup is too thin, there are several easy ways to thicken it. First, simmer uncovered for a few extra minutes to reduce the liquid. Alternatively, you can create a slurry by mixing 1 tbsp cornstarch with 2 tbsp cold water, then stirring it into the soup and simmering for 2-3 minutes until thickened. Another option is to add more cheese—Parmesan or cream cheese works well to enhance creaminess and thickness. For a heartier texture, consider mashing a small portion of the cooked noodles and stirring them back into the soup. Be cautious not to over-thicken, as the soup should remain velvety and spoonable.

Can You Make Alfredo Lasagna Soup in a Crockpot?

Yes, this soup adapts beautifully to a crockpot! To make it, brown the sausage and sauté the onion and garlic in a skillet first, then transfer to the crockpot. Add the broth, broken lasagna noodles, and Italian seasoning. Cook on low for 4-5 hours or high for 2-3 hours until the noodles are tender. About 30 minutes before serving, stir in the Alfredo sauce, heavy cream, spinach, and Parmesan, and heat through. The crockpot method is perfect for hands-off cooking, but avoid adding the cream and cheese too early to prevent curdling. Adjust seasoning before serving.

What Noodles for Lasagna Soup?

Traditional lasagna noodles, broken into bite-sized pieces, are the classic choice for this soup, giving it that authentic lasagna feel. However, you can experiment with other noodles for different textures. Mafalda (mini lasagna noodles) is a fantastic alternative, mimicking the lasagna shape in a smaller form. Bowtie (farfalle) or penne work well for a sturdy bite, while egg noodles offer a softer texture. For gluten-free diets, use gluten-free lasagna noodles or rice-based pasta. Avoid overly delicate noodles like angel hair, as they may become mushy. Cook noodles just until al dente to maintain the perfect texture in the soup.

Is Alfredo Soup Good for Leftovers?

Yes, Alfredo lasagna soup is excellent for leftovers! The flavors deepen as it sits, making it a great option for meal prep. However, the noodles may absorb some broth over time, so the soup might thicken. To counteract this, store extra broth separately and add it when reheating. The soup stays fresh in the fridge for up to 3 days, and the creamy Alfredo base holds up well, provided it’s stored properly.

How to Store Leftover Lasagna Soup

To store leftover Alfredo lasagna soup, cool it to room temperature to prevent condensation. Transfer to an airtight container and refrigerate for up to 3 days. If you anticipate leftovers, consider cooking the noodles separately and adding them to individual portions to prevent them from becoming soggy. Store the soup base and noodles separately in the fridge, combining them when ready to serve.

Does Lasagna Soup Freeze Well?

Yes, Alfredo lasagna soup freezes well, but with a caveat. The creamy Alfredo base can sometimes separate when frozen due to the high dairy content. To minimize this, omit the cream and cheese when preparing the soup for freezing. Freeze the soup base (sausage, broth, noodles, and veggies) in a freezer-safe container for up to 3 months. When ready to eat, thaw in the fridge overnight, then reheat and add the cream, Alfredo sauce, and cheese during the final heating stage to restore the creamy texture.

How to Reheat Creamy Lasagna Soup

To reheat, pour the soup into a saucepan and warm over medium-low heat, stirring occasionally to prevent the cream from separating. Add a splash of broth or cream if the soup has thickened. For microwave reheating, use a microwave-safe bowl, cover loosely, and heat in 1-minute intervals, stirring between each, until warmed through. Avoid boiling to maintain the smooth texture of the Alfredo sauce. If reheating frozen soup, thaw it first for even heating.
