Introduction

This Cheeseburger Spaghetti Squash Casserole is a comforting, low-carb dinner that combines the flavors of a classic cheeseburger with tender spaghetti squash. It’s easy to prepare and perfect for a family meal that feels indulgent without the extra carbs.

A white plate holds two main sections: on the left is a cheesy casserole with visible layers including cooked mushrooms and ground meat topped with melted yellow cheddar cheese, which looks gooey and slightly browned; on the right is a fresh mixed green salad with leafy greens of different shades of green and purple, sliced red and yellow cherry tomatoes adding pops of color, and a light dressing. A silver fork rests on the plate near the casserole. The plate sits on a white marbled surface, next to a soft blue-green cloth napkin. In the background, another similar plate is partially visible with the same food items. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 large spaghetti squash (750g), cooked and shredded
1 medium yellow onion (220g), diced
8 oz. mushrooms, roughly chopped
1 lb. 96/4 ground beef
1 14.5 oz can diced tomatoes, drained
4 oz. reduced-fat cream cheese (112g), softened
1 Tbsp steak seasoning
1/4 tsp salt
1 cup shredded cheddar cheese (112g), divided

Instructions

Step 1: Preheat the oven to 375 degrees F and spray a 9×13-inch baking dish with cooking spray.
Step 2: Spray a skillet with cooking spray, then add the diced onions and chopped mushrooms. Cook over medium heat for 4-5 minutes until tender. Drain any excess liquid and transfer the veggies to a large bowl.
Step 3: In the same skillet, add the ground beef and cook over medium heat until browned, breaking it into pieces as it cooks. Drain off excess fat.
Step 4: Add the cooked beef, diced tomatoes, softened cream cheese, half of the shredded cheddar cheese, salt, and steak seasoning to the bowl with the veggies. Mix everything well to combine evenly.
Step 5: Transfer the mixture to the prepared baking dish and spread it out evenly. Sprinkle the remaining cheddar cheese over the top.
Step 6: Bake for 20-25 minutes until the cheese on top is melted and bubbly. Remove from the oven and let it cool slightly before serving.

Tips & Variations

For extra flavor, add a splash of Worcestershire sauce to the beef while cooking.
Try using other types of cheese such as mozzarella or pepper jack for a different twist.
If you want to add some veggies, diced bell peppers or spinach work well mixed into the casserole.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm individual portions in the microwave until heated through, or reheat in a 350°F oven covered with foil for about 15 minutes.

How to Serve

The casserole looks creamy and textured with the ingredients spread evenly across three to four layers. In the background, there is a white bowl filled with shredded yellow cheese, and the whole setup is placed on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7
