Manwich casserole transforms classic sloppy Joe sauce and ground beef into an easy, cheesy family bake. This protein-rich, budget-friendly dinner is a fun weeknight shortcut that kids devour.
Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with olive oil.
Heat 2 tbsp olive oil in a skillet over medium-high heat, then sauté onion and bell pepper for 3–4 minutes until softened.
Add ground beef to the skillet and cook, breaking apart, until browned and fully cooked; drain excess fat for best texture.
Stir in Manwich sauce, garlic powder, salt, and black pepper; simmer for 5 minutes over medium heat to meld flavors.
Meanwhile, boil egg noodles in salted water until just al dente (about 6 minutes); drain well to prevent a watery bake.
Layer half the noodles in the baking dish, followed by half the beef mixture, then sprinkle 1 cup shredded cheddar cheese; repeat layers and finish with the remaining cheese.
Bake uncovered for 20–25 minutes, until the cheese is bubbling and golden; rest for 5 minutes before slicing and serving for perfect casserole structure.
