I’ve made this slow cooker creamy tortellini soup on a rainy weeknight more times than I can count — it’s one of those recipes that feels like a warm blanket in a bowl. This version uses pantry-friendly ingredients, a hands-off slow cooker, and finishes with cream and Parmesan for a silky finish. It’s perfect when you want comfort without fuss, and it adapts easily for vegetarian or meat-loving households.

Why you’ll love this dish

This soup checks so many boxes: cozy, quick to assemble, budget-friendly, and family-approved. The slow cooker melds tomatoes, onion, garlic, and herbs into a flavorful base while you go about your day. Fresh or frozen tortellini turns it into a satisfying, pasta-forward meal without needing to babysit a pot. Add spinach at the end for a bright color and extra nutrients.

"One pot, minimal prep, and everyone asks for seconds — the perfect weeknight rescue."

It’s also a great recipe to scale up for potlucks or scale down for two. If you like similar easy slow-cooker comfort meals, you might enjoy this slow-cooker chicken noodle soup for another hands-off classic.

The cooking process explained

Before you open the slow cooker, here’s what happens: the broth, tomatoes, onion, garlic, and dried herbs simmer slowly to build depth. Spinach goes in near the finish so it stays bright. Tortellini—fresh or frozen—should be added toward the end so it cooks perfectly and doesn’t turn mushy. Finally, stirring in cream and Parmesan at low heat gives the soup a velvety texture that clings to pasta.

Timing expectations:

Prep time: 10–15 minutes.
Slow-cooker base: 2–4 hours (high/low options).
Tortellini and finish: 20–30 minutes more.
Total active time: ~15 minutes.

Gather these items

What you’ll need:

1 (16 oz) package cheese tortellini (fresh or frozen) — fresh or frozen both work; frozen holds up better for longer simmering.
4 cups vegetable broth (or chicken broth) — use low-sodium if you plan to salt later.
1 (15 oz) can diced tomatoes, undrained.
1 onion, diced.
2 cloves garlic, minced.
2 cups fresh spinach, chopped.
1/2 teaspoon dried basil.
1/2 teaspoon dried oregano.
1/4 teaspoon ground black pepper.
1/2 cup heavy cream (or half-and-half for a lighter finish).
1/2 cup grated Parmesan cheese.
Salt to taste.
Fresh basil or parsley for garnish (optional).

(Substitutions/notes: swap vegetable broth for chicken broth if not vegetarian; use light cream or half-and-half to reduce richness; shredded mozzarella or Asiago can complement or replace Parmesan.)

Directions to follow

Prep onion and garlic: Dice the onion and mince the garlic.
Add base ingredients to slow cooker: Place broth, diced tomatoes (with juices), diced onion, minced garlic, dried basil, dried oregano, and black pepper in the slow cooker. Stir to combine.
Cook the base: Cover and cook on low for 3–4 hours or on high for 2–3 hours, until the onion is tender and flavors are melded.
Add tortellini: Stir in the tortellini. If using fresh tortellini, add during the last 20 minutes on high; if frozen, allow 25–30 minutes. Check for doneness — tortellini should be al dente.
Finish with greens and dairy: Stir in the chopped spinach, heavy cream (or half-and-half), and grated Parmesan. Let heat through on low for 5–10 minutes until the spinach wilts and the soup is warmed through. Taste and add salt as needed.
Serve: Ladle into bowls and garnish with fresh basil or parsley and extra Parmesan, if desired.

Quick tips: avoid overcooking tortellini by adding it at the end. If soup becomes too thick, thin with extra broth or water.

Best ways to enjoy it

Serving suggestions:

Ladle the soup into shallow bowls and top with a drizzle of extra-virgin olive oil and a sprinkle of cracked black pepper.
Serve with crusty bread or garlic bread to soak up the broth.
A simple arugula salad with lemon vinaigrette cuts the richness and adds freshness.
For a heartier meal, serve alongside baked pasta like this comforting slow-cooker baked ziti.

Plating idea: place a nest of tortellini in the center of each bowl, spoon broth around, then add greens and cheese last so they pop visually.

Storage and reheating tips

Refrigerate: Cool soup to room temperature (no more than 2 hours at room temp) then store in airtight containers for 3–4 days.
Reheat: Warm on the stove over medium-low, stirring gently. Heat to at least 165°F (74°C) for safety. If the soup thickens, add a splash of broth or water.
Freeze: You can freeze the soup, but tortellini may become softer after thawing. For best texture, freeze the base (without tortellini and cream) for up to 3 months. Thaw, reheat, then add fresh tortellini and cream and cook until the tortellini is tender.

Food-safety note: refrigerate within two hours of serving. Avoid repeatedly reheating and cooling large batches.

Helpful cooking tips

Use low-sodium broth to control saltiness and season at the end.
If you like a smoother broth, use an immersion blender briefly before adding tortellini to blend some of the tomatoes and onion.
For a deeper flavor, sauté the onion and garlic in a pan briefly before adding to the slow cooker.
Add tortellini only near the finish — it cooks quickly and will disintegrate if left in the slow cooker for hours.
To make this vegetarian, ensure your Parmesan is vegetarian-friendly (some contain animal rennet) or use a vegetarian hard cheese alternative.

Creative twists

Sausage version: Brown Italian sausage and add it to the slow cooker for a meaty boost (see a similar sausage-tortellini idea in this external recipe below for inspiration).
Tomato-creamy swirl: Stir in a tablespoon of tomato paste when cooking the base for a richer tomato flavor.
Dairy-free: Swap heavy cream for canned coconut milk and use nutritional yeast instead of Parmesan for a dairy-free option.
Greens swap: Substitute kale or Swiss chard for spinach; add earlier so tougher greens soften.
Spicy kick: Add red pepper flakes or a splash of hot sauce when finishing.

FAQ

How long should I cook the soup in a slow cooker?
- Cook the base on low for 3–4 hours or high for 2–3 hours. Add tortellini during the last 20–30 minutes so it cooks properly without becoming mushy.
Can I use frozen tortellini?
- Yes. Frozen tortellini works well; add it a bit earlier (about 25–30 minutes before serving) so it warms through and cooks fully.
Is this soup freezer-friendly?
- The broth and vegetables freeze well, but tortellini’s texture changes after freezing. For best results, freeze the base without tortellini and add fresh or frozen tortellini when reheating.
Can I make this dairy-free or lighter?
- Substitute half-and-half or a non-dairy milk (unsweetened almond or oat) for a lighter finish. For dairy-free, use coconut milk and nutritional yeast for a cheesy flavor.
How do I prevent the tortellini from getting soggy?
- Add tortellini at the end of cooking and avoid long, unattended simmering after it’s added. If making ahead, cook tortellini separately and combine just before serving.
