This Sausage Tortellini Soup has Italian sausage, cheese tortellini, and spinach in a rich tomato broth. Hearty, flavorful, and perfect for weeknight dinners.
Heat oil in a large pot or Dutch oven over medium-high heat. Add diced onion and sauté for 3-4 minutes until softened.
Add Italian sausage and garlic. Cook, breaking the sausage into pieces, until browned and no longer pink, about 4-5 minutes. Drain any excess grease.
Stir in crushed tomatoes, broth, basil, salt, and pepper. Bring to a boil, then reduce heat to low. Cover and simmer for 20-30 minutes.
Add tortellini and cook for 5 minutes, or until pasta is tender.
Stir in spinach, cover, and turn off heat. Let sit for 1-2 minutes until spinach is wilted.
Serve topped with Parmesan cheese and a cheesy crostini if desired.
For Crostini (Optional): Slice baguette into ½-inch thick pieces. Butter one side and place butter-side down in a hot skillet until golden. Flip, top with Parmesan, and cook until the other side is golden. Cover briefly if needed to melt cheese.
Notes
Don't overcook the tortellini. Add it in the last 5-10 minutes. It will turn mushy if it simmers too long.
For leftovers: Cook tortellini separately and add to individual bowls. Store soup and pasta in separate containers to prevent mushy pasta.
Make it creamy: Stir in ½ to 1 cup heavy cream when you add the tortellini.
Sausage swap: Ground chicken, turkey, or beef all work. Add Italian seasoning if using plain ground meat.
Frozen or dried tortellini: Adjust cooking time based on package directions. Frozen may need 2-3 extra minutes.
Balance acidity: If the tomatoes taste too acidic, add a small pinch of sugar.
Add more veggies: Sauté diced carrots and celery with the onion for extra nutrition.
Slow cooker option: Brown sausage first, then cook soup base on LOW 3-4 hours. Add tortellini in last 30 minutes, spinach in last 5-10 minutes.
Freezing: Freeze soup base without tortellini for up to 3 months. Add fresh tortellini when reheating.
Reheating: Warm gently on stovetop. Add a splash of broth if it has thickened.
