Step-by-Step Instructions

Preheat the Oven:

Set your oven to 375 degrees Fahrenheit and give it plenty of time to reach temperature. This allows for a perfectly even bake and a golden, bubbling top.

Cook the Bacon:

Place the diced bacon in a large skillet over medium heat. Let it sizzle until the fat renders and the edges get really crisp—these bits will become irresistible nuggets in the finished casserole. Remove with a slotted spoon and reserve the grease.

Sauté the Aromatics:

With the bacon fat still in the pan, toss in the finely chopped onion and minced garlic. Keep the heat at medium and stir regularly for two to three minutes. Watch for the onions to turn translucent and the garlic to become fragrant but not browned.

Brown the Beef:

Add ground beef to the pan with the aromatics. Stir frequently and break up clumps as it cooks until all traces of pink are gone and you see some brown bits for extra flavor. Drain excess grease so the casserole does not become oily.

Combine the Beef and Bacon:

Return your crisp bacon to the pan and fold it into the beef mixture. Set aside and let cool off the heat for a few minutes so the eggs do not scramble in the next step.

Mix the Custard:

In a large mixing bowl, whisk together eggs, heavy cream, yellow mustard, Worcestershire, salt, and black pepper. Whisk thoroughly until no streaks of egg remain and the mixture is completely smooth.

Layer in the Baking Dish:

Lightly grease an eight by eight inch baking dish. Spread the beef and bacon mixture evenly in the pan, pushing it to the corners for an even layer.

Add Cheese and Custard:

Sprinkle one cup of shredded cheddar cheese all over the meat mixture to create the melty base layer. Slowly pour the egg custard mixture on top, letting it flow evenly over all the cheese and meat.

Finish with Cheese:

Scatter the remaining cheddar cheese over the top. Aim for full coverage so each bite gets extra gooey and the top bakes up golden and rich.

Bake:

Place the casserole on the middle oven rack and bake for twenty five to thirty minutes or until the center is set and the cheese on top is bubbling and deeply golden at the edges.

Rest and Serve:

Take the casserole out and let it rest for five minutes. This helps the custard finish setting so you can cut tidy slices. Add chopped green onions and tomatoes on top just before serving for fresh flavor and color.

One of my favorite ingredients here is the smoky bacon—it always reminds me of lazy weekend brunches and is so satisfying in every bite. My family loves gathering around the table for this casserole, and we always laugh about racing for the corner pieces with the crispiest cheddar crust.

Storage Tips

Once cooled, cover the baking dish with plastic wrap or foil and refrigerate for up to four days. For longer storage, cut into portions and freeze individually. To reheat, use a low oven so the custard does not overcook and the cheese stays nice and melty. If using the microwave, heat in short bursts and let it rest between rounds.

Ingredient Substitutions

If you want to lighten the dish, swap turkey bacon or use half ground turkey with half ground beef. You can also change up the cheese—Swiss or Monterey Jack both melt beautifully and add new character. For extra veggies, add sauteed mushrooms or diced bell peppers right into the beef mixture after browning.

Serving Suggestions

This casserole is wonderful with a bright, crunchy salad tossed in vinaigrette. We also love it with fresh avocado or a little sugar free ketchup on the side for burger authenticity. If extra hungry, serve alongside simple roasted zucchini or cauliflower rice to keep things low carb but satisfying.
