Ingredients Method

Ingredients

  

• 1.5 pounds (680 g) ground beef (80/20 or 85/15 works best)
• 6 slices thick-cut bacon, chopped
• 1 small onion, diced
• 3 cloves garlic, minced
• 1 cup dill pickles, chopped (plus extra slices for topping, optional)
• 1 tablespoon yellow mustard (or Dijon for a sharper kick)
• 2 tablespoons sugar-free ketchup (or tomato paste plus a pinch of sweetener)
• 1 teaspoon smoked paprika
• 1/2 teaspoon ground black pepper
• 1/2 teaspoon sea salt (adjust to taste; bacon can be salty)
• 4 large eggs
• 1/2 cup heavy cream (or full-fat coconut milk for dairy-free)
• 2 cups shredded cheddar cheese (divided)
• 2 tablespoons cream cheese, softened (optional for extra creaminess)
• 2 tablespoons olive oil or avocado oil (if needed)
• 2 cups riced cauliflower (fresh or frozen), squeezed dry
• 2 green onions, sliced (for garnish)
• Red pepper flakes or hot sauce (optional)

Method

 

1. Preheat and prep: Heat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
2. Crisp the bacon: In a large skillet over medium heat, cook the chopped bacon until crisp. Transfer to a paper towel–lined plate. Leave about 1 tablespoon bacon fat in the pan.
3. Sauté aromatics: Add the diced onion to the skillet. Cook 3–4 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
4. Brown the beef: Add ground beef. Break it up and cook until no longer pink, about 6–8 minutes. Drain excess fat if very greasy.
5. Season the mixture: Stir in mustard, sugar-free ketchup, smoked paprika, pepper, and salt. Fold in chopped pickles and half the cooked bacon. Simmer 2 minutes to blend flavors.
6. Add cauliflower rice: Mix in riced cauliflower. Cook 2–3 minutes to steam off moisture. Taste and adjust salt or mustard.
7. Make the custard: In a bowl, whisk eggs, heavy cream, and cream cheese (if using) until smooth. Stir in 1 cup shredded cheddar.
8. Assemble: Spread the beef mixture evenly in the baking dish. Pour the egg-cheese mixture over the top. Sprinkle with remaining 1 cup cheddar and the rest of the bacon.
9. Bake: Bake 20–25 minutes, until the center is set and the top is bubbly and golden around the edges.
10. Garnish and rest: Let it rest 10 minutes. Top with sliced green onions and extra pickle slices if you like.
11. Portion for meal prep: Cut into 6–8 squares. Cool completely before sealing in containers.

Storage Instructions

• Refrigerator: Store portions in airtight containers for up to 4 days.
• Freezer: Wrap portions tightly or vacuum-seal.

  Freeze up to 2 months. Thaw overnight in the fridge.

• Reheating: Microwave 60–90 seconds per piece, or bake at 325°F (165°C) for 12–15 minutes until warmed through. Cover with foil to keep the top from over-browning.
• Moisture control: If freezing, place a paper towel under the lid to catch steam after reheating, then remove before eating.

Health Benefits

• Keto-friendly macros: Low in net carbs thanks to cauliflower rice and no bun, helping keep you in ketosis.
• Steady energy: Protein and fat help stabilize appetite and reduce mid-afternoon crashes.
• Nutrient support: Eggs and dairy provide vitamin D, B12, and calcium; beef adds iron and zinc.
• Customizable fats: You can lean up the dish with 90/10 beef or keep it more satiating with 80/20, based on your goals.

What Not to Do

• Don’t skip draining or drying: Excess grease or wet cauliflower will make the casserole soggy.
• Don’t overseason with salt early: Bacon, cheese, and pickles add salt.

  Taste before adding more.

• Don’t use too much ketchup: Regular ketchup adds sugar. Stick to sugar-free or use tomato paste.
• Don’t cut it hot: Let it rest so the custard sets. Cutting too soon makes messy slices.
• Don’t forget to label: For meal prep, mark containers with date and servings to avoid waste.

Alternatives

• Protein swaps: Use ground turkey, chicken, or bison.

  Add 1 tablespoon olive oil if using lean meat to avoid dryness.

• Dairy-free: Substitute full-fat coconut milk for cream, use dairy-free cream cheese, and top with a melty vegan cheese alternative.
• Veggie boost: Add chopped mushrooms, bell peppers, or spinach. Sauté thoroughly to cook off moisture before baking.
• Spicy version: Stir in jalapeños, chipotle powder, or a splash of hot sauce. Pepper jack cheese also works well.
• Bunless “special sauce” drizzle: Mix mayo, sugar-free ketchup, mustard, and a pinch of paprika.

  Drizzle after reheating to keep it fresh.

• No cauliflower: Skip it and reduce the cream by 2 tablespoons; the casserole will be denser but still tasty.

FAQ

Can I make this casserole ahead and bake later?

Yes. Assemble it up to 24 hours in advance, cover tightly, and refrigerate. Let it sit at room temperature for 15–20 minutes, then bake as directed, adding 5 extra minutes if it’s very cold.

How do I keep it from getting watery?

Dry your cauliflower rice well, sauté off moisture, and drain excess beef fat.

Let the casserole rest before slicing so the custard sets and releases steam.

What cheese works best if I don’t have cheddar?

Monterey Jack, Colby Jack, or a blend of cheddar and mozzarella melt beautifully. For stronger flavor, try sharp cheddar or smoked gouda.

Is this kid-friendly?

Usually yes. If serving kids, go easy on the pickles and paprika, then offer condiments on the side.

Many kids love the bacon and cheesiness.

How many servings does this make?

A 9×13-inch dish yields 6–8 servings, depending on appetite and sides. For meal prep, plan on 6 hearty portions.

What can I serve with it?

Try a simple green salad, roasted broccoli, or sliced avocado. A quick slaw with mayo, vinegar, and celery salt pairs nicely too.

Can I cook the bacon in the oven instead?

Absolutely.

Bake at 400°F (205°C) for 15–18 minutes on a lined sheet until crisp. Crumble and proceed with the recipe.
