Ingredients

Onion - Sweet onions and yellow onions are always a good idea.

Cloves garlic - Minced garlic is delicious, and garlic powder is always a viable option also.

Ground beef - My family likes ground beef in this recipe instead of the traditional lamb.

Zucchini - Clean well and slice!

Crushed tomatoes - Canned tomatoes save on prep but you can use fresh tomatoes if you want.

Salt and pepper - To taste.

Cauliflower - You can buy the cauliflower already diced or dice it yourself.

Butter - Adds richness and flavor.

Heavy cream - This adds flavor and thickness to the pie.

Shredded cheese - You can use any type of cheese that you want.

How to Make Keto Shepherd's Pie

The complete instructions and ingredient quantities are under the photos in the recipe card.

Step One: Heat the olive oil in a large saucepan. Add the onion and garlic and sauté on medium heat until soft and translucent.

Step Two: Add the ground beef and cook over medium-high heat, stirring frequently, until it is browned and cooked through.

Step Three: Add the zucchini and tomatoes and stir to combine.

Step Four: Reduce the heat to a simmer. Simmer uncovered for 10 minutes.

Step Five: In a large pot, add cauliflower to boiling water. Boil the cauliflower until soft, about 8-10 minutes.

Step Six: Drain the cauliflower, allowing all steam to escape. Dry cauliflower will help make a creamier mash.

Step Seven: Transfer the drained cauliflower florets to a food processor. Add the butter, cream, shredded cheese, salt, and pepper. Process until smooth.

Expert Tip: If you don't have a food processor you can process the cauliflower in a blender in small batches.

Step Eight: Place the ground beef mixture in the bottom of a large casserole dish. Top with the cauliflower.

Expert Tip: If you use a cast iron skillet to cook the beef you can leave it right in the skillet and add the mashed cauliflower on top.

Step Nine: Bake at 350F for 20-25 minutes and until the filling is bubbly and the topping is browned.

Variations

Add a garnish - Adding fresh parsley right on top is a great flavor!

Vegetables - You can boost the vegetables by adding some chopped celery and carrots with the onions. They will increase the net carbs slightly though.

Mix in cream cheese - To get a super creamy cauliflower mash, add a tad bit of cream cheese to the mixture. You can also add an egg yolk to set the cauliflower more.

Bold flavor - If you like a stronger tomato flavor stir some tomato paste into the ground beef. You can also add a dash of worcestershire sauce to boost the flavor of the meat.

Protein source - If you want to cut down on calories and fat content, lower-fat ground turkey, ground venison, or ground chicken works in place of ground beef.

Common Questions

What is in Shepherd's Pie?

Shepherd's pie is a traditional dish that most likely originated in Scotland or northern England. It was a recipe developed to use leftover pieces of roast meat. It is usually called "shepherd's pie" when made with lamb because a shepherd looks after sheep.

Shepherd's pie is traditionally made with ground lamb. However, I used ground beef in this low carb version because my family prefers it, and it is easier for me to find. This is normally called Cottage Pie. That said, if you love lamb and are able to find it in your local grocery store, please feel free to substitute it for ground beef.

How do you make Shepherd's Pie keto?

Traditional shepherd's pie is a casserole made with a layer of cooked meat and vegetables in a savory gravy. Then, the meat is topped with mashed potatoes, and baked in the oven until the mashed potatoes are browned.

This keto shepherd's pie is made with mashed cauliflower topping instead of mashed potatoes. "Cauli mash" is a great low carb or Trim Healthy Mama alternative to mashed potatoes -- and is just as delicious. It has more fiber, nutrition, and a lot fewer carbs than potatoes. I like to use cheddar cheese in my cauliflower for a boost of flavor.

How do I store leftovers?

The leftovers of this hearty dish are the best! Just let the low carb shepherd’s pie mixture cool down and then store it in an airtight container. Reheat in the microwave and add some freshly shredded cheese on top, if you'd like!

What goes with Shepherd's Pie?

This dish is almost a full meal in itself. Meat, veggies, and cauliflower mash come together to make a satisfying meal.

If you are looking to make something to accompany it, I'd suggest garlic broccoli or a simple side salad.

Can I make this ahead of time?

Yes, you can make this up to 2 days ahead of time. Make the meat mixture and mashed cauliflower and assemble the keto shepherds pie casserole. When you are ready to serve it bake it as directed.
