How to Make Slow Cooker Stuffed Shells with Meat

Follow these straightforward steps for flawless results every time. Total hands-on preparation takes just 45 minutes.

Step 1: Create the Tomato Base

Heat olive oil in a skillet over medium. Add onions and sauté until translucent – about 5 minutes. Stir in garlic and optional crushed red pepper, cooking 1 minute until fragrant. Pour in crushed tomatoes and tomato sauce. Season with 1 teaspoon salt and 1/2 teaspoon pepper. Simmer uncovered for 20 minutes, stirring occasionally.

Step 2: Mix the Cheese Filling

While sauce simmers, combine ricotta, 1 cup mozzarella, provolone, Parmesan, egg, remaining garlic, 1/2 teaspoon salt, 1/4 teaspoon pepper, and parsley in a bowl. Transfer mixture to a large plastic bag and snip one corner to create a piping bag. This hack makes filling shells mess-free.

Step 3: Assemble in Slow Cooker

Spread 1 cup marinara sauce in your slow cooker. Pipe cheese filling into uncooked shells, arranging them in a single layer. Top with remaining sauce and reserved mozzarella. Carefully pour water around the edges (not directly on top) to help pasta cook properly.

Step 4: Cook to Perfection

Cover and cook on high for 3-4 hours or low for 5-6 hours. Check shells at the earliest time – they should be tender but firm. Remove lid, sprinkle with fresh parsley and basil, then let rest 10 minutes before serving. For another delicious slow-cooked meat option, try our tangy pulled beef alongside these cheesy shells.

FAQs About Slow Cooker Stuffed Shells

Why add water around the shells?

Water creates steam to properly cook pasta without making sauce watery. Pour gently along slow cooker edges.

How do I prevent shells from sticking?

Always spray slow cooker with non-stick spray before adding sauce. Arranging shells in single layer also helps.

Absolutely. Assemble unbaked shells in slow cooker insert, cover and refrigerate overnight. Add 30 minutes to cooking time.
