How I Make Slow Cooker Mushroom Spinach Tortellini
Step 1
I add the butter, olive oil, onions, garlic, mushrooms, vegetable broth, Italian seasoning, thyme, onion powder, salt, and pepper to my slow cooker.
Step 2
I cover and cook on Low for 5–6 hours or High for 2½–3 hours, until the mushrooms are tender and flavorful.
Step 3
About 30 minutes before serving, I stir in the refrigerated tortellini.
Step 4
Next, I add the spinach, heavy cream, cream cheese, and Parmesan. I stir until everything is well combined and the cheeses melt into a creamy sauce.
Step 5
If I’d like an even thicker sauce, I stir in the cornstarch slurry and let everything cook for another 10–15 minutes.
Step 6
I finish with chopped parsley, extra Parmesan, and plenty of cracked black pepper before serving.
Tips for Success
- Slice the mushrooms evenly so they cook at the same rate.
- Freshly grated Parmesan melts much smoother than pre-shredded cheese.
- Don’t add the tortellini too early or it can become overly soft.
- Baby bella mushrooms add the deepest flavor, but white mushrooms work wonderfully too.
- Taste before serving and adjust the seasoning if needed.
Variations I Love
Add Protein
Sometimes I stir in:
- Rotisserie chicken
- Shredded chicken breasts
- Italian sausage
- Crispy bacon
More Vegetables
This recipe is also delicious with:
- Sun-dried tomatoes
- Frozen peas
- Roasted red peppers
- Kale instead of spinach
Make It Lighter
For a lighter version, I substitute half-and-half for the heavy cream. The sauce isn’t quite as rich, but it’s still delicious.
What I Serve With It
This creamy pasta pairs perfectly with:
- Garlic bread
- Caesar salad
- Roasted broccoli
- Simple green salad
- Crusty artisan bread
Storage
I store leftovers in an airtight container in the refrigerator for up to 3 days.
When reheating, I add a splash of milk or broth to loosen the sauce since it thickens as it sits.
I don’t recommend freezing this recipe because the cream sauce and tortellini can change texture after thawing.
