Low-Carb Bacon Cheeseburger Casserole Ingredients
For the Casserole Base
• Ground Beef – a hearty, protein-rich foundation that captures classic burger flavors; substitute with ground turkey for a leaner option.
• Bacon – adds that delightful smoky crunch; consider using turkey bacon for a lighter, low-carb twist.
• Onion – sautéed, it provides sweetness and aroma; swap for shallots if you prefer a milder flavor.
• Garlic – boosts the savory richness; fresh garlic is ideal, but powdered garlic works in a pinch.
For the Creamy Custard
• Eggs – essential for creating the creamy custard that binds everything together; egg substitutes can also work for a dairy-free option.
• Heavy Cream – ensures a rich, velvety texture; use almond milk or coconut milk for a lighter version.
• Yellow Mustard – adds that signature tang; Dijon mustard can elevate the flavor if you’re feeling adventurous.
• Worcestershire Sauce – infuses a burst of umami; soy sauce is a great substitute for a gluten-free recipe.
• Salt & Black Pepper – fundamental seasonings to enhance the overall flavor profile.
For the Cheesy Topping
• Shredded Cheddar Cheese – provides the gooey cheesiness beloved in any cheeseburger; any melting cheese can work, including dairy-free options.
Optional Garnishes
• Chopped Green Onions – adds a fresh touch and a pop of color; they enhance the presentation.
• Diced Tomatoes – brighten the dish visually and add a juicy contrast; totally optional but recommended for freshness.

Step‑by‑Step Instructions for Low-Carb Bacon Cheeseburger Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This step ensures your Low-Carb Bacon Cheeseburger Casserole will bake evenly, achieving that perfect golden-brown top and bubbling interior. While the oven warms, gather your ingredients and baking equipment for a seamless cooking experience.
Step 2: Cook the Bacon
In a large skillet, cook diced bacon over medium heat until it reaches a crispy texture, about 5–7 minutes. Use a slotted spoon to transfer the crispy bacon to a plate, leaving the delicious bacon grease behind in the skillet. This grease will add richness to the casserole as you continue to cook.
Step 3: Sauté the Aromatics
In the same skillet with the bacon grease, add the chopped onion and minced garlic. Sauté for about 2–3 minutes until the onion is translucent and fragrant, stirring occasionally to prevent burning. The aromatic mixture will infuse your Low-Carb Bacon Cheeseburger Casserole with savory flavors.
Step 4: Brown the Ground Beef
Next, add the ground beef to the skillet, breaking it up with a spatula. Cook until it’s browned and no longer pink, approximately 5–7 minutes. Once cooked, carefully drain any excess grease from the skillet, ensuring a deliciously moist casserole without being too greasy.
Step 5: Combine Ingredients
Stir in the previously cooked bacon, mixing well with the ground beef, onions, and garlic. Allow the mixture to cool slightly while you prepare the custard base. This cooling step ensures the eggs won’t scramble when combined with the warm meat mixture in the Low-Carb Bacon Cheeseburger Casserole.
Step 6: Prepare the Egg Mixture
In a large mixing bowl, whisk together the eggs, heavy cream, yellow mustard, Worcestershire sauce, and a sprinkle of salt and pepper. Whisk until the mixture is smooth and well combined. This creamy custard will bind the casserole, creating that delightful texture everyone loves.
Step 7: Layer the Casserole
Grease an 8×8-inch baking dish with cooking spray or a bit of olive oil. Layer the ground beef mixture evenly in the dish, ensuring that it covers the bottom completely. This foundational layer is crucial for the Low-Carb Bacon Cheeseburger Casserole’s structure and flavor.
Step 8: Add Cheese
Sprinkle 1 cup of shredded cheddar cheese evenly over the beef layer. The cheese will melt beautifully during baking, creating a gooey, comforting topping that enhances the cheeseburger experience in every bite.
Step 9: Pour in the Egg Mixture
Carefully pour the egg mixture over the layered beef and cheese, allowing it to sink slightly into the layers. This step ensures that every forkful of the Low-Carb Bacon Cheeseburger Casserole is packed with flavor and moisture, binding everything together perfectly.
Step 10: Top with Remaining Cheese
Finish off your casserole with the remaining cheddar cheese, spreading it evenly across the top. This extra layer of cheese will create a deliciously melty topping, giving your Low-Carb Bacon Cheeseburger Casserole that irresistible cheeseburger appeal.
Step 11: Bake the Casserole
Place the baking dish in the preheated oven and bake for 25–30 minutes. It’s done when the casserole is set, bubbly, and the top is golden brown. Keep an eye on it during the last few minutes for that perfect browning.
Step 12: Cool Before Serving
Once baked, remove the casserole from the oven and let it cool for a few minutes before slicing. This brief cooling period helps the custard set properly, making it easier to serve and enjoy. Garnish with chopped green onions or diced tomatoes if desired, and dig into this delicious Low-Carb Bacon Cheeseburger Casserole!

Expert Tips for Low-Carb Bacon Cheeseburger Casserole
