Ingredients
Olive oil – You can also use coconut oil or avocado oil as well. These are good healthy fat alternatives.
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.
Top 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.
Top 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 golden brown.
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 cream cheese to the mixture. Sour cream works as well. 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 keto cottage pie 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.

I doubled the recipe and it took an extra 15 minutes to brown
What a great recipe! I just got done eating and I’m so stuffed but want more. That’s how good it is! Thank you! #keto
I added a beef bullion cube to the hamburger mixture to make it beefier, loved it
I love this recipe, I added some Italian sausage to it extra garlic it’s awesome , will make again
I’m going to add a cube, as well. Thanks.
I have not tried it but it seems like an egg wash might help brown the cauliflower
I love this recipe! I just made it, but I couldn’t get the mashed cauliflower to brown, I even left it in for an extra 5 minutes. Only the edges started to brown. Can anyone offer me what I might have missed or any tips to making it brown better?
You could put it under the broiler for a couple minutes.
Add some cheese
put a little cheese on top and broil for 6 minutes
I found the easiest way to brown cauliflower in the oven is to add a some real Parmesan cheese(not the stuff in the big green plastic container) the fresh stuff even the stuff that’s pre-shredded works well. It is a much drier cheese then say cheddar or mozzarella so it seems to brown a lot faster then either of those without adding a lot of fat that tends to float on top. Anyway that worked wonderful for me!
Going to try the addition of a beef bullion cube to add a depth of flavour have to check the sodium content on those first.
You certainly did mention it is ‘technically’ Cottage Pie in the beginning but lots of people just glaze over to the recipe. It’s a great recipe!! I very much like adding Worcestershire sauce. As for the cauliflower mash, I bought a colander with very tiny fine holes. It’s important to get as much liquid out of the cauliflower once cooked, (called ricing) which renders a truly creamy texture which is very close to mashed potatoes!! I use a bowl to press it in the colander to release the water. Less water should allow it to brown better, too.
Thanks for sharing your tips, Mary! I’m glad you like this recipe 🙂
Has anyone tried Nthis with frozen mashed cauliflower?
can I add peas, green beans and corn to this and get the same carb count?
No, those all have carbs. Green beans would be the best choice.
I’m about to prepare this but was curious why it is listed as American cuisine instead Irish or United kingdom?
Because it’s not a traditional recipe, just my take on it.
This recipe is awesome. I hope it re heats well.
thank you for the recipe I will be making the base and freezing to have on hand.
So good. I bought two of the green giant sour cream and chives mashed cauliflower. Mixed it with 1/2 pound of pre cooked bacon diced. Loaded it up with Monterrey jack cheese, like 3/4 pound. Baked for 25 min then broiled for 2 minutes to crisp it up. So much better than our old style potato/ corn/ ground beef. I also added some chili powder and basil on top before broiling. My wife hasn’t spoken to me in the last 15 minutrs due to consumption of said recipe. Lol. So good. Thank you.
It turned out really good. I used diced tomatoes instead and added the whole can rather than having some leftover and because I love cheese I put in one cup of cheddar.
I’m so excited to make this tonight! My son’s allergic to dairy, though, so we’re going to try with ghee, almond milk and nutritional yeast. Fingers crossed it works! Have you tried to make this ahead, refrigerate, then bake? Would this work?? Thanks in advance!
My fave for dairy free cauliflower is butter flavored coconut oil. It should be fine to make ahead.
Excellent recipe and a great keto replacement for shepard’s pie, thank you SO much. You method of making the topping will be my go to for ‘mashed potatoes’ now. It is delicious. There are a few heavy carb recipes that tend to be my triggers, this was one. Now that I have a keto option though for all my trigger foods I am in for the long haul. #KetoOn my friends!
This was AMAZING! I did the cauliflower in the vitamix, only 30 seconds!! I used pepper jack cheese. Seriously this was so flipping good even my cauliflower hating husband ate it. We made 4 servings rather than 6 for 9 net carbs and I don’t feel bad about it! XOXO
Can I freeze this?
I have not frozen it yet but I think it would freeze well.
