Ingredients

1 pound ground beef
1/2 cup diced onion
1 (16 ounce) jar spaghetti sauce, or more to taste
1/2 (8 ounce) package cream cheese, softened
1/2 (8 ounce) container sour cream
cooking spray
1 (12 ounce) package wide egg noodles

Preparation

Heat a large skillet over medium heat. Cook and stir beef and onion in the hot skillet until beef browns and onion softens, 5 to 7 minutes. Drain and discard grease.
Add spaghetti sauce, cream cheese, and sour cream to the skillet. Mix well.
Spray a 5-quart slow cooker with cooking spray. Layer noodles, beef mixture, and cheeses in the slow cooker. Repeat layers as necessary until cooker is full.
Cover and cook on High for 2 hours. Switch to Low and cook until noodles are soft and cheeses are melted, about 2 hours more.
