Ingredients

For the Meat Base:

  • 1 ½ lbs (680g) ground beef (80/20 recommended for flavor and moisture)

  • 1 medium yellow onion, finely diced

  • 2 cloves garlic, minced

  • 1 teaspoon kosher salt

  • ½ teaspoon black pepper

For the “Special Sauce” Layer:

  • ½ cup (120g) sugar-free ketchup

  • ¼ cup (60g) mayonnaise (full-fat, no added sugar)

  • 2 tablespoons yellow mustard

  • 1 tablespoon sugar-free pickle relish

  • 1 teaspoon smoked paprika

  • ½ teaspoon onion powder

For the Layered Fillings:

  • 6 large eggs

  • ½ cup (120ml) heavy cream

  • 4 cups (about 6 oz) fresh cauliflower rice (or 1 (12 oz) bag frozen, thawed and squeezed dry)

  • 8 dill pickle sandwich slices, chopped

  • 2 cups (8 oz) shredded sharp cheddar cheese, divided

  • 1 cup (4 oz) shredded Monterey Jack or Colby Jack cheese

  • Optional Toppings for Serving: Crispy cooked bacon crumbles, sliced green onion, diced tomato, extra pickles, avocado

Equipment

  • Large, oven-safe skillet (like cast iron) OR a 9×13 inch baking dish and a separate skillet

  • Mixing bowls

  • Whisk

  • Paper towels (for cauliflower, if frozen)

Instructions

Step 1: Brown the Beef and Aromatics

Preheat your oven to 350°F (175°C).
If using an oven-safe skillet, place it over medium-high heat. Add the ground beef and diced onion. Cook, breaking up the meat with a spoon, until the beef is no longer pink and the onions are softened, about 7-8 minutes.
In the last minute, add the minced garlic, salt, and pepper. Stir and cook until fragrant. If there’s excess grease, you can carefully drain some off, but leave a little for moisture.

Step 2: Create the Burger “Special Sauce”

In a small bowl, whisk together the sugar-free ketchup, mayonnaise, mustard, pickle relish, smoked paprika, and onion powder until smooth and combined.
Pour this sauce over the cooked meat in the skillet. Stir until everything is evenly coated. Remove from heat. If you’re not using an oven-safe skillet, transfer the saucy meat mixture into a greased 9×13 inch baking dish and spread it into an even layer.

Step 3: Prepare the Cauliflower & Cheese Layers

If using frozen cauliflower rice, ensure it is completely thawed. Place it in a clean kitchen towel or several layers of paper towels and squeeze out as much moisture as possible. This is critical to prevent a watery casserole.
Sprinkle the dried cauliflower rice evenly over the meat layer in the skillet or dish.
Scatter the chopped pickles evenly over the cauliflower.
In a medium bowl, whisk together the eggs and heavy cream until smooth. Season with a pinch of salt and pepper.
Carefully pour the egg mixture evenly over the entire dish, aiming to cover as much surface area as possible. Gently shake the dish to help the eggs settle into the layers.

Step 4: The Cheesy Blanket

In a bowl, combine 1 ½ cups of the shredded cheddar with all of the Monterey Jack cheese.
Sprinkle this cheese blend evenly over the entire top of the casserole.
Finish by sprinkling the remaining ½ cup of cheddar cheese on top.

Step 5: Bake to Bubbly, Golden Perfection

Place the skillet or baking dish in the preheated oven.
Bake, uncovered, for 35-40 minutes. The casserole is done when the edges are bubbling vigorously, the top is a deep, golden brown, and the center is set (no longer jiggly when you gently shake the dish).

Step 6: Rest, Garnish, and Serve

Remove the casserole from the oven and let it rest for 5-10 minutes. This allows the layers to set, making it easier to slice and serve.
Garnish with your favorite burger toppings: a sprinkle of crispy bacon, sliced green onions, diced fresh tomato, or extra pickles.
Serve hot directly from the dish, scooping out hearty portions that include all the delicious layers.

Chef’s Notes & Keto Success Tips

  • Cauliflower Rice is Key: Squeezing all possible moisture from the cauliflower rice is the #1 trick to avoid a soggy bake. Fresh riced cauliflower tends to have less water than frozen.

  • Sugar-Free Staples: Read labels carefully on ketchup, mayonnaise, and relish. Many contain hidden sugars like high-fructose corn syrup. Primal Kitchen and G Hughes are popular keto-friendly brands.

  • Cheese Choice: Shred your own cheese from a block. Pre-shredded cheese contains starches and anti-caking agents that can hinder melting and add hidden carbs.

  • Customize Your “Burger”:

    • Bacon Cheeseburger: Add ½ cup of cooked, crumbled bacon to the meat layer.

    • Mushroom Swiss: Sauté 1 cup of sliced mushrooms with the onions. Use Swiss cheese in place of Monterey Jack.

    • Spicy Western: Add ¼ cup of diced jalapeños (pickled or fresh) and use Pepper Jack cheese.

  • Make Ahead & Meal Prep: Assemble the entire casserole (unbaked), cover tightly, and refrigerate for up to 24 hours. Let it sit at room temperature for 20 minutes before baking, and you may need to add 5-10 minutes to the bake time. Leftovers reheat beautifully.

Storage & Reheating

  • Storage: Cool completely, then cover and refrigerate for up to 4 days.

  • Reheating: Reheat individual portions in the microwave for 60-90 seconds. For a larger portion, reheat in a covered oven-safe dish at 350°F (175°C) for 15-20 minutes, or until heated through.

Why This Recipe is Perfect for Keto

This casserole cleverly replaces the bun with a stable, nutritious layer of cauliflower rice bound with eggs and cream. It provides the same handheld satisfaction of a burger in a fork-friendly format, all while keeping net carbohydrates low and healthy fats high to support ketosis. The “special sauce” delivers that iconic flavor without the sugar spike.
