In a large skillet over medium heat, brown the ground beef until fully cooked, about 5-7 minutes. Drain excess fat, return skillet to heat, stir in pasta sauce and garlic powder, simmer for 5 minutes.

Spread a thin layer of the meat sauce mixture in the bottom of your crockpot. Layer half of the frozen cheese ravioli on top, followed by another layer of meat sauce. Repeat, finishing with a layer of meat sauce.

Sprinkle mozzarella cheese over the final meat sauce layer followed by cheddar and Parmesan cheese. Ensure even distribution for best texture.

Cover the crockpot and cook on low for 4-5 hours or high for 2-3 hours until ravioli are fork-tender and cheese is bubbling.

Remove lid and let sit for 10-15 minutes before serving to help layers set.
