How to Make Slow-Cooker Million-Dollar Stuffed Shells
Prepare the Filling: In a large bowl, combine the cottage cheese, shredded mozzarella, cream cheese, Parmesan, beaten egg, and crushed red pepper flakes. Mix until well blended and creamy.
Cook the Beef: In a skillet over medium heat, brown the lean ground beef until fully cooked, approximately 7-10 minutes. Once cooked, drain any excess fat and set aside.
Combine Sauces: Add the tomato basil pasta sauce and water to the browned beef in the skillet. Stir and simmer for about 5 minutes to meld the flavors.
Stuff the Shells: Carefully fill each jumbo pasta shell with a generous scoop of the cheese mixture. Be sure to fill them well but not overstuffed.
Layer and Assemble: In your slow cooker, spread half of the beef and sauce mixture evenly on the bottom. Place the stuffed shells in a single layer on top, then pour the remaining sauce over the shells.
Add Cream: Drizzle the heavy whipping cream over the top of the assembled shells for extra richness and creaminess.
Cook: Cover and cook on low for 4-6 hours, or on high for 2-3 hours, until the shells are tender and the flavors have melded beautifully.
Optional: Serve with fresh basil or a sprinkle of extra Parmesan cheese on top for added flavor.
