What is Shepherd’s Pie?

The specific country responsible for the creation of Shepherd’s pie is disputed. However, it is safe to say it originated in the British Isles. This recipe is basically a casserole with cooked meat and vegetables topped with mashed potatoes. In the states, ground beef is the most common meat used with this recipe, but in the British Isles this would be called a “cottage pie” while a Shepherd’s pie uses ground lamb.

While this recipe traditionally uses a mashed potato topping, we will use a cauliflower topping for this version. There are thousands of traditional Shepherd’s pie recipes out there, but we wanted to create a version that had the same great taste but with much fewer calories and carbs.

  • Avocado oil: We prefer avocado oil for this recipe but olive oil or any neutral oil will work.
  • Vegetables: For this recipe we are loading up on tons of fresh veggies including onion, garlic cloves, frozen peas, cauliflower and carrots.
  • Lean ground beef: at least 90% lean, you can also use ground turkey or chicken in this recipe.
  • Beef broth and tomato paste: a high quality broth makes a noticeable difference in the flavor
  • Worcestershire sauce: key component of Shepherd’s pie flavor
  • Herbs and Spices: Fresh rosemary, thyme and parsley. Spices include garlic powder, salt and pepper.
  • Unsalted butter: Adds flavor and thickens the topping. You can also use salted if that is all you have on hand, you may want to reduce the salt the recipe calls for to accommodate.
  • Grated parmesan cheese: Adds flavor and thickens the topping.

How to Make Healthy Shepherd’s Pie

Aside from the ingredients listed above you will need a large skillet or dutch oven and a pot. You will also need a cutting board and knife. Follow the step-by-step directions below or scroll to the recipe card.

Saute Onions

Heat the oil over medium heat in a large pot or Dutch oven. Add the onion and saute until translucent, about 2-3 minutes. Add the garlic and saute another minute. The onions will continue to cook with the ground beef, so it is okay if they are not all the way soft yet.

Brown the Ground Beef

Add the ground beef to the skillet and brown, breaking it up as you go. If you used a cut of ground beef with a higher fat content and need to drain off the grease do so when the meat has been cooked through.

Simmer

Add the beef broth, Worcestershire sauce, tomato paste and stir until combined and no lumps remain. Bring to a simmer and simmer for 10-15 minutes or until the sauce has reduced and thickened. Then add the frozen vegetables, herbs and spices. Stir until combined. Then set aside. Preheat oven to 400 degrees.

Make the cauliflower topping

Make the cauliflower topping by bringing a pot of water to a boil, then steaming the cauliflower with a steamer basket for about 10-15 minutes, or until fork mashable. Drain and transfer the cauliflower to a large bowl, blender, or food processor, and add the butter, grated parmesan cheese, garlic powder, salt, and pepper. Use an immersion blender, blender, or food processor to blend until smooth. 

Bake

Pour the meat mixture into a greased 8×8 casserole dish. Top with the mashed cauliflower, spreading it evenly over the meat mixture. Place the baking dish on a baking sheet (to prevent spills) and bake in the preheated oven for 30-35 minutes. Allow to cool slightly, then serve!

Serve

Allow the casserole to sit for 5-10 minutes before you cut into it. This allows for the sauce to cool and thicken.

Notes

  • This is one of the most flavorful shepherd’s pies I’ve ever eaten. Full of herb flavor, and not a huge cauliflower taste, either.
  • To keep this as “light” as possible, I used 93% lean ground beef. I would suggest using at least 90% lean ground beef if not leaner to keep it from being too oily.
  • Leftovers keep in the fridge for up to 3 days. This also would make a great freezer meal!
  • This recipe makes 6 servings, and each slice measures about 4″ x 2.6″ in the 8×8 pan. Each slice has 9.5 net carbs.
