How to Make Slow Cooker Jumbo Shells

1. Add the dry pasta

Spread the uncooked jumbo shells evenly across the bottom of your slow cooker. Try to keep them in a relatively even layer so they cook consistently.

2. Add the sauce and water

Pour the pasta sauce and water over the dry shells. Make sure the liquid is distributed as evenly as possible so the pasta has enough moisture to become tender.

3. Slow cook the pasta

Cover the slow cooker and cook on LOW for 3 to 4 hours, checking around the 3-hour mark. Cooking times can vary depending on the slow cooker, so check the shells toward the end of the cooking time.

If the pasta appears too dry before becoming tender, add a small splash of water.

4. Add the mozzarella

Once the shells are tender, sprinkle the shredded mozzarella evenly over the top. Cover and cook for another 10 to 15 minutes, or until the cheese is completely melted.

Serve the cheesy jumbo shells warm with a green salad, garlic bread, or steamed vegetables.

Tips for the Best Slow Cooker Jumbo Shells

Keep the shells evenly distributed. An even layer helps the pasta cook at a similar rate throughout the slow cooker.

Check early. Slow cookers can vary considerably. Start checking the pasta around the 3-hour mark to prevent overcooking.

Use your favorite sauce. Marinara, traditional pasta sauce, or a smooth tomato sauce can all work well. A smooth sauce is especially suitable for picky eaters.

Add Italian seasoning for extra flavor. If you are not strictly limiting the recipe to four ingredients, a little Italian seasoning or garlic powder can give the sauce an extra boost.

Make it heartier. For a more substantial dinner, add cooked ground beef, cooked Italian sausage, or spoonfuls of ricotta before serving.

Serve it family-style. Keep the slow cooker on the warm setting after the cheese melts so everyone can help themselves.
