3. Shepherd’s Pie with a Cauliflower Mash Topping

Traditional Shepherd’s Pie is already comforting, but we’re making it even better for a high-protein fall diet.

This recipe uses lean ground lamb or beef in a rich, savory gravy with vegetables, and swaps the standard potato topping for a lighter, protein-boosted cauliflower and white bean mash.

• For the Filling:
  • 1.5 lbs lean ground lamb or beef
  • 1 large onion, chopped
  • 2 carrots, diced
  • 2 celery stalks, diced

  • 2 tablespoons tomato paste
  • 1 cup beef broth
  • 1 cup frozen peas
  • 1 teaspoon fresh thyme or rosemary, chopped

Add broth and herbs, bring to a simmer, and cook for 10 minutes until slightly thickened. Stir in the frozen peas.

4. Spread the cauliflower mash evenly over the meat filling in the skillet. Use a fork to create some texture on top.
5. Bake for 20-25 minutes, or until the filling is bubbly and the topping is lightly golden. You can broil for the last 1-2 minutes for extra browning.

Protein Punch: Ground lamb, beef, and the clever addition of cannellini beans in the mash make this dish a protein powerhouse.
