Let’s Get Cooking! Step-by-Step Instructions

This low-carb cheeseburger casserole is easy to throw together, even on busy nights. Here’s how I make it:

1. Preheat and Prep

Preheat your oven to 350°F (175°C).
Grease a 9×13 inch baking dish with cooking spray or a little butter.

2. Brown the Beef

In a large skillet over medium heat, cook the ground beef until fully browned.
Drain the excess grease (I usually leave just a little for flavor).

3. Add Onion and Garlic

Toss in the diced onion and minced garlic.
Sauté for 2–3 minutes, until the onion softens and the garlic smells amazing.

4. Season the Meat

Add in the salt, pepper, paprika, and oregano.
Stir and cook for another minute to bring out the flavors.

5. Make the Sauce

In a small bowl, mix together the sugar-free ketchup, mustard, and mayonnaise.
Add this to the skillet and stir to coat everything evenly.

This is where it starts smelling like an actual cheeseburger—trust me.

6. Transfer to Baking Dish

Pour the meat mixture into your prepared baking dish.
Spread it out evenly with a spatula.

7. Add the Bacon

Sprinkle the crumbled bacon over the beef layer.

8. Add the Eggs

In a clean bowl, whisk the eggs until smooth.
Pour evenly over the meat and bacon.

9. Top with Cheese

Sprinkle the top with cheddar and mozzarella cheese. I like to do a mix for that perfect melt.

10. Bake It

Bake uncovered for 25–30 minutes, until the cheese is melted and bubbly and the eggs are set.

Let it sit for 5–10 minutes before slicing—it firms up and slices like a dream.

Recipe Tips & Add-Ins

Want to customize your casserole? Go for it. This recipe is super flexible.

You can:

• Add chopped pickles on top after baking
• Mix in a handful of chopped spinach for extra veggies
• Use ground turkey or even ground chicken if that’s what you have
• Try adding cream cheese to the sauce for extra creaminess (try 2 oz!)
• Add a dash of hot sauce or red pepper flakes if you like a little heat

Bonus tip: It also makes great muffin-style mini casseroles. Just portion into a greased muffin tin and reduce baking time to 18–20 minutes.

What to Serve with Low-Carb Cheeseburger Casserole

It’s a complete meal on its own, but if you want sides, here are some great low-carb options:

• Simple side salad with ranch or blue cheese
• Roasted broccoli or cauliflower
• Zucchini fries or baked green beans
• Cauliflower mash for comfort-food vibes
• Or even just some pickle spears on the side (highly recommend)

How to Store & Reheat Leftovers

This casserole is meal-prep gold. It reheats beautifully and even freezes well.

• Fridge: Store in an airtight container for up to 4 days
• Freezer: Freeze individual slices in freezer bags for up to 2 months
• Reheat: Microwave on 50% power to avoid overcooking, or bake covered at 300°F until warmed through

Sometimes I make a double batch just to have extra portions for lunch!
