Red Meat

March 6, 2026

Craving ultimate comfort food without the carbs? This Keto Shepherd’s Pie is your answer! We’ve swapped traditional potatoes for a velvety, creamy cauliflower mash and packed the savory beef filling with rich mushrooms and onions. Topped with crispy bacon, it’s a hearty, satisfying meal that will have everyone asking for seconds. Perfect for a cozy weeknight dinner!

Ingredients

• 8 slices uncooked bacon / approx. 225g
• 1 medium head cauliflower / approx. 2 lbs or 900g, chopped
• ¼ cup / 60ml canned full-fat coconut milk
• Salt and freshly ground black pepper, to taste
• 2 pounds / 900g ground beef, 80% lean
• 8 ounces / 225g mushrooms, sliced
• 1 large yellow onion, chopped
• 2 cloves garlic, minced

Instructions

1. Directions
2. Preheat your oven to 375°F / 190°C. In a large, oven-safe skillet, cook the bacon over medium heat until crispy. Transfer the bacon to a paper towel-lined plate, leaving about 1 tablespoon of grease in the skillet. Once cooled, crumble or chop the bacon.
3. While the bacon cooks, bring a large pot of salted water to a boil. Add the chopped cauliflower and cook until fork-tender, about 6-8 minutes. Drain the cauliflower very well and transfer it to a food processor. Add the coconut milk, a pinch of salt, and pepper. Blend until completely smooth and creamy. Set aside.
4. Return the skillet with the bacon grease to medium-high heat. Add the ground beef and cook, breaking it apart with a spoon, until browned. Drain off any excess fat.
5. Add the chopped onion, sliced mushrooms, and minced garlic to the beef. Cook for 5-7 minutes, until the vegetables have softened. Season the mixture with salt and pepper to taste.
6. Transfer the beef and vegetable mixture to a 9×13 inch baking dish, spreading it in an even layer. Spoon the cauliflower mash over the top and spread it to cover the filling completely.
7. Bake for 25-30 minutes, until the filling is hot and bubbly. For a golden-brown top, switch the oven to a high broil for the final 2-3 minutes, watching carefully to prevent burning.
8. Let the casserole rest for 5 minutes before serving. Sprinkle the crumbled bacon over the top and enjoy.

Pro Tips

• for Success
• For the creamiest cauliflower mash, ensure you drain the boiled cauliflower extremely well. Patting it dry with paper towels after draining removes excess moisture that can make it watery.
• To deepen the flavor of the beef filling, add a tablespoon of tomato paste and a teaspoon of Worcestershire sauce (or coconut aminos) when you add the vegetables.
• This casserole can be fully assembled up to 24 hours in advance. Cover and refrigerate, then add 10-15 minutes to the baking time when you’re ready to cook.
