This simple Slow Cooker Lasagna Soup is everything you love about classic lasagna—rich tomato flavor, hearty protein, cheesy goodness—but made so much easier in one cozy slow cooker pot.

It comes together in minutes and slowly simmers into a thick, comforting soup (honestly closer to a stew!) that’s perfect for those chilly, rainy PNW days. With tender tortellini, hidden spinach, and a creamy finish, it’s a meal the whole family will love—no layering required.
We love serving it with a slice of tangy, rustic sourdough bread to soak up every last bit.
There’s something about a warm pot of soup simmering on the stove that instantly makes a home feel cozy.
So put on your Apron First and let’s get started!

Ingredients
Ground Turkey (1–2 lbs) – Lean protein that absorbs all the rich flavors

Garlic (2–3 cloves) – Adds savory depth
Onion (1 medium) – Builds the base flavor
Salt & Pepper – To taste
Red Pepper Flakes (1 tsp, optional) – Adds a gentle heat
Stewed Tomatoes (2 × 15 oz cans) – Creates a rich, hearty base
Cream Cheese (8 oz, cubed) – Adds creaminess and richness
Chicken Broth (4 cups) – Balances and thins the soup
Fresh Spinach (3–4 cups) – Blended for a hidden veggie boost
Tortellini (1 package, ~9–12 oz) – Adds cheesy, hearty texture (fresh, frozen, or dried)
