Essential Ingredients

Ground Beef: Use lean ground beef for less grease; aim for 80/20 for the best flavor.
Cheddar Cheese: Grate fresh cheddar for optimal meltiness; avoid pre-shredded varieties.
Eggs: Eggs help bind the ingredients together; use large ones for consistency.
Heavy Cream: Adds richness and creaminess; feel free to substitute with sour cream if desired.
Onion: Sautéed onion adds a sweet depth of flavor; yellow onions work best here.
Bell Peppers: Feel free to mix colors for a vibrant appearance; they add crunch and sweetness.
Ketchup (sugar-free): A tangy kick that brings the classic burger experience without the carbs.
Dijon Mustard: Just a touch elevates the flavor profile; opt for smooth Dijon over grainy.
Garlic Powder: For an aromatic punch, garlic powder is essential; fresh garlic can also be used.
Salt and Pepper: Season generously to bring out every flavor; adjust according to your taste preferences.

Let’s Make it together
Preheat Your Oven: Preheat your oven to 350°F (175°C). Prepare a baking dish by greasing it lightly with cooking spray to prevent sticking.
Sauté the Veggies: In a skillet over medium heat, add diced onions and bell peppers. Cook until they soften and become fragrant, around 5 minutes.
Brown the Beef: Add ground beef to the skillet, breaking it apart as it cooks. Stir until browned completely, about 7-10 minutes. Drain excess fat if necessary.
Add Flavor Boosters: Stir in garlic powder, salt, pepper, ketchup, and mustard into the beef mixture until well combined. The aroma will be irresistible!
Mix Everything Together: In a bowl, whisk together eggs and heavy cream until blended. Then combine this mixture with the beef and veggie mix thoroughly.
Add Cheese & Bake!: Pour half of the beef mixture into your prepared baking dish. Sprinkle half of the cheddar cheese on top before adding the remaining beef mixture. Finish with more cheese on top! Bake for 30-35 minutes until bubbly and golden brown.
Enjoying this keto cheeseburger casserole will feel like giving your taste buds a warm hug on a chilly evening! It’s comforting yet healthy—who knew being on keto could taste so indulgent?
