Tips for a Creamy, Cheesy Casserole

Here are some friendly tips to make your Easy Keto Hamburger Casserole extra creamy, cheesy, and flavorful every time you make it.

• Soften your cream cheese: Take it out about 30 minutes before you start so it blends effortlessly into the beef.
• Don’t overcook the beef: Brown it just until it’s no longer pink. Overcooked beef can get dry and take away from the creamy texture.
• Add veggies: Feel free to stir in diced bell peppers or mushrooms (for inspiration, see Creamy Mushroom Mozzarella Bake) to boost the nutrition and add a little extra flavor.
• Use fresh shredded cheese: Pre-shredded cheese often has anti-caking additives that can affect melt quality. Fresh is best for that ooey-gooey topping.
• Rest before serving: Let the casserole sit a few minutes after you pull it from the oven to help it set up and make serving easier.
