Step-by-Step Instructions
Making Slow Cooker Spinach and Ricotta Stuffed Shells is simple, with minimal effort for a cheesy, comforting dish. Follow these steps for a delicious result.
Step 1: Cook the Pasta
- Cook 12 jumbo pasta shells in a large pot of boiling salted water according to package instructions until al dente (usually 8–10 minutes).
- Drain, rinse with cold water to stop cooking, and set aside to cool slightly.
- Tip: Undercook by 1–2 minutes to ensure shells stay firm during slow cooking.
Step 2: Prepare the Filling
- In a medium bowl, mix 2 cups ricotta cheese, 1 cup chopped fresh spinach, ½ cup grated Parmesan cheese, 1 tsp Italian seasoning, and a pinch of salt and pepper until well-combined.
- Tip: If using frozen spinach, thaw and squeeze out excess water to avoid a watery filling.
Step 3: Stuff the Shells
- Carefully stuff each cooled pasta shell with about 2 tbsp of the ricotta-spinach mixture, using a spoon or piping bag for ease.
- Place the stuffed shells in a single layer in the slow cooker, open side up.
- Tip: Work gently to avoid tearing the shells, and ensure they’re snug but not overcrowded.
Step 4: Add Sauce and Cheese
- Pour 2 cups marinara sauce evenly over the stuffed shells, covering them well.
- Sprinkle 1 cup shredded mozzarella cheese over the top.
- Tip: Reserve a little sauce to serve on the side if you like an extra saucy dish.
Step 5: Cook
- Cover and cook on low for 4–5 hours or high for 2–3 hours, until the shells are heated through, the cheese is melted, and the sauce is bubbly.
- Check doneness at the lower end of the time to avoid overcooking, as slow cookers vary.
- Tip: Avoid lifting the lid during cooking to maintain consistent heat.
Step 6: Serve
- Carefully scoop out the stuffed shells with a large spoon, ensuring each portion includes sauce and melted cheese.
- Serve hot, garnished with fresh basil leaves or chopped basil if desired.
- Tip: Pair with a side salad or garlic bread for a complete Italian meal.
Assembly
Assembling Slow Cooker Spinach and Ricotta Stuffed Shells is all about creating a cheesy, inviting plate. Here’s how to bring it together:
- Serve the Stuffed Shells: Carefully scoop 2–3 stuffed shells per plate, ensuring they’re coated with marinara sauce and melted mozzarella.
- Garnish: Sprinkle with fresh basil leaves or chopped basil for a pop of color and freshness.
- Presentation Tips:
- Use wide, shallow plates to showcase the vibrant red sauce and golden cheese against the shells.
- Arrange shells neatly in a row or cluster for a polished look, or serve family-style in a large dish.
- Pair with a side of Caesar salad, roasted zucchini, or crusty bread for a complete Italian-inspired meal.
Tip: For a buffet-style presentation, keep the shells warm in the slow cooker and set out extra sauce, cheese, and garnishes for guests to customize.

A: Yes! Use ½ cup frozen spinach, thawed and squeezed dry to remove excess water, to prevent a watery filling.
