Ingredients You’ll Need
With just a handful of everyday ingredients, this casserole delivers big cheeseburger flavor and unbeatable coziness. Each item in the Keto Cheeseburger Casserole Recipe earns its spot, bringing something special to the taste, creaminess, or deliciously golden top layer.
- Ground Beef: Rich, juicy, and foundational to that signature cheeseburger taste—opt for 80/20 for best flavor, but lean works too.
- Diced Onion: Brings a gentle sweetness and depth; just a half onion is enough to round out the flavor.
- Garlic: Two cloves, minced, add a hit of aroma and a subtle bite—don’t skip it!
- Salt and Black Pepper: The basic duo that ties everything together while letting all the other flavors shine through.
- Mustard Powder: Just a teaspoon, but it’s the secret ingredient that gives those unmistakable burger vibes.
- Tomato Paste: Adds a rich, slightly tangy note while helping bind the filling and deepen the color.
- Dill Pickles: Chopped for easy bites, they add classic cheeseburger tang and an irresistible crunch.
- Eggs: Four whisked eggs transform everything into a creamy, set casserole—you’ll hardly believe it’s low carb.
- Heavy Cream: Adds silkiness to the eggs, keeping the custard rich and satisfying.
- Shredded Cheddar Cheese: The melty, sharp blanket that makes each bite gooey and full of comfort.
- Shredded Mozzarella Cheese: For extra stretch and a milder cheese pull, this is your best friend.
- Chopped Parsley or Green Onions (optional): A fresh, colorful garnish that wakes up every serving—especially if you want to impress guests.
How to Make Keto Cheeseburger Casserole Recipe
Step 1: Prepare Your Baking Dish and Preheat the Oven
Start by preheating your oven to 375°F and lightly greasing an 8×8-inch baking dish. This ensures your casserole comes out easily and gets that beautiful golden edge that’s so satisfying, both visually and in every bite.
Step 2: Brown the Beef with Onions and Garlic
In a large skillet over medium heat, cook the ground beef with diced onion and garlic. Stir frequently to let the onion soften and the beef brown and cook through—this usually takes about 6 to 8 minutes. If there’s a lot of fat, be sure to drain off the excess for a lighter, less greasy casserole.
Step 3: Season and Add Flavor
Once the beef is browned, stir in the salt, black pepper, mustard powder, tomato paste, and chopped pickles. Everything will start smelling like your favorite burger spot, but with a fun twist. Let the mixture heat for another minute or two to blend all those savory flavors.
Step 4: Transfer Beef Mixture to Baking Dish
Scoop the beef mixture into your prepared baking dish, spreading it out evenly. This creates the flavor-packed base for your Keto Cheeseburger Casserole Recipe, and ensures every layer will cook just right.
Step 5: Mix and Pour the Egg Custard
In a separate bowl, whisk together the eggs and heavy cream until smooth and a little frothy. This mixture adds structure, creaminess, and that classic casserole feel without any heavy carbs. Pour the egg mixture gently over the beef mixture—jiggle the pan a little to distribute it evenly.
Step 6: Layer on the Cheese
Sprinkle the shredded cheddar and mozzarella cheeses evenly over the top. The blend of sharp and mild cheeses guarantees a bubbly, golden top that you’ll want to dig right into.
Step 7: Bake to Golden Perfection
Slide the casserole into your preheated oven and bake for 25 to 30 minutes, or until it’s set and the cheese is gorgeously golden and bubbly. If you love a bit more browning, you can broil it for an extra minute, but watch closely!
Step 8: Rest, Garnish, and Serve
Let your freshly baked Keto Cheeseburger Casserole Recipe rest for 5 minutes straight out of the oven. This helps everything firm up—making it easier to serve beautiful, cheesy squares. Garnish with chopped parsley or green onions if you’re feeling fancy or just want that burst of fresh color.
How to Serve Keto Cheeseburger Casserole Recipe
Garnishes
A sprinkle of chopped parsley or green onions adds an eye-catching finish and a pop of bright, fresh flavor. For a real cheeseburger vibe, you can also top each slice with an extra dollop of sugar-free ketchup, a swipe of grainy mustard, or a couple of extra pickle slices.
Side Dishes
This casserole is dreamy with light, crisp sides to balance all its oozy goodness. Think a simple green salad with lemony vinaigrette, steamed broccoli, or roasted Brussels sprouts. If you want to keep things classic, serve it alongside a pile of sliced tomatoes and crunchy lettuce—just like your favorite burger platter, but keto-style.
Creative Ways to Present
Feeling playful? Cut the casserole into squares and serve in lettuce cups for handheld bites. Or turn mini portions into sliders by stacking them with extra pickles on little toothpicks. For family-style fun, pile up scoops on a platter and let everyone garnish their own plate—the options with this Keto Cheeseburger Casserole Recipe are delightfully endless.
Make Ahead and Storage
Storing Leftovers
Transfer any leftovers into airtight containers and stash them in the fridge. The flavors only improve overnight, and the casserole stays creamy and satisfying for up to 4 days—making your next meal a breeze.
Freezing
If you want to get ahead, make the Keto Cheeseburger Casserole Recipe, let it cool, and wrap tightly before freezing. It keeps beautifully for up to 2 months. Just defrost in the fridge overnight before reheating so the textures stay lovely.
Reheating
For best results, reheat single portions in the microwave for 1 to 2 minutes or until hot throughout. To maintain that just-baked texture for larger portions, pop the dish back in the oven at 350°F for about 10 to 15 minutes, covered loosely with foil to prevent over-browning.
FAQs
Can I substitute the ground beef in the Keto Cheeseburger Casserole Recipe?
Absolutely! Ground turkey or chicken are fantastic substitutes if you’re craving something lighter, while ground pork gives a richer twist. Just keep an eye on liquid content and drain as needed for a perfect set.
Is this casserole spicy?
The recipe as written is mild, but you can spice things up by adding a pinch of chili powder or red pepper flakes, or even topping your slice with jalapeños if you love some heat.
Can I make this dairy-free?
It takes some tweaking, but you can sub in your favorite non-dairy cheese shreds and swap heavy cream for unsweetened cashew or coconut cream. Just know the flavor will shift a bit, but the spirit of the Keto Cheeseburger Casserole Recipe will still shine through.
How can I meal-prep with this casserole?
This dish is a meal-prepper’s dream! Assemble everything ahead and store unbaked in the fridge for up to 24 hours, or bake, cool, and portion into containers for easy grab-and-go lunch or dinner all week long.
What toppings are best for customizing each serving?
Classic cheeseburger toppings work beautifully here: diced tomato, shredded lettuce, sliced jalapeños, and extra pickles. You can also let everyone at the table pick their favorites for a truly interactive and fun dinner experience.
