Ingredients

• 1 pound ground beef
• 1 (2.25 ounce) can sliced black olives, drained
• 1 (8 ounce) package uncooked egg noodles
• 1 (16 ounce) jar spaghetti sauce, or as needed

Recipe Instructions

Step 1

Preheat the oven to 375 degrees F (190 degrees C).

Step 2

Bake in the preheated oven until casserole is bubbling, 30 to 45 minutes.

Step 3

Add ground beef to a skillet over medium heat; cook until no longer pink, breaking beef apart into crumbles as it cooks, about 10 minutes.

Step 4

Fill a large pot with lightly salted water and bring to a rapid boil. Cook egg noodles at a boil until tender yet firm to the bite, about 5 minutes; drain.

Step 5

Combine beef, noodles, 1/2 mozarella cheese, spaghetti sauce, pepperoni, black olives, and mushrooms in a large bowl; transfer to a 9x13-inch baking dish. Top with remaining 1/2 cheese. Cover the dish with aluminum foil.
