1. Directions
2. Preheat your oven to 350°F / 177°C.
3. Heat the olive oil in a large skillet over medium heat.
4. Add the ground beef, celery, onion, and garlic. Cook for 8–10 minutes, breaking up the meat with a spoon, until the beef is browned and the veggies are soft.
5. Carefully drain any excess fat from the skillet.
6. Stir in the chopped tomatoes and remove the skillet from the heat.
7. Spread the meat mixture evenly into the bottom of a 10×7-inch casserole dish.
8. To make the topping, combine the cooked and drained riced cauliflower, cheddar cheese, Parmesan cheese, heavy cream, and dried thyme in a food processor.
9. Pulse until the mixture is smooth and creamy, resembling mashed potatoes.
10. Spoon the cauliflower mash over the meat layer, spreading it evenly to the edges.
11. Bake for 35–40 minutes, or until the topping is golden brown and the filling is bubbling.
12. Let the casserole rest for 5-10 minutes before serving. This helps it set.
13. Slice, serve, and enjoy your delicious keto comfort meal!

Pro Tips

• Squeeze the cooked, riced cauliflower in a cheesecloth or clean kitchen towel to remove as much water as possible. This is the key to a firm, not soggy, topping.
• For a deeper flavor, add a tablespoon of tomato paste and a splash of sugar-free Worcestershire sauce to the meat mixture along with the tomatoes.
• Don’t over-process the cauliflower topping. Pulse just until it’s combined and creamy to avoid a watery texture.
• For an extra-browned and bubbly cheese crust, switch the oven to broil for the last 1-2 minutes of cooking, watching carefully to prevent burning.

FAQ

Q: Is this Shepherd’s Pie recipe truly keto-friendly
A: Yes, absolutely. This recipe is specifically designed for a keto diet by replacing high-carb potatoes with a cauliflower mash. Each serving contains only 5.7 grams of net carbs.

Q: How do I prevent the cauliflower topping from being watery
A: The most crucial step is to squeeze as much water as possible from the cooked, riced cauliflower using a cheesecloth or a clean kitchen towel. This ensures a firm, creamy topping instead of a soggy one.

Q: Can I use a different meat instead of ground beef
A: While the recipe uses ground beef (making it technically a Cottage Pie), traditional Shepherd’s Pie is made with ground lamb, which would be an excellent keto-friendly substitution. Ground turkey would also work.

Q: How can I get an extra crispy cheese topping
A: For a more golden-brown and bubbly cheese crust, you can switch your oven to the broil setting for the last 1-2 minutes of cooking. Be sure to watch it carefully to prevent it from burning.
