Shepherd’s Pie With Lentils + Sweet Potato


Shepherd’s Pie is a favorite in many households in Britain. It was a way for people to use up scraps of meat and veggies. It’s a delicious and budget-friendly meal! I made this low-carb version using cauliflower and sweet potatoes for the topping, and replaced meat with protein-rich lentils! BONUS: it fits my meal plan for my latest fitness/nutrition program!

1 1/2 cups (any) lentils, dry

3 Carrots, medium (diced)

3 stalks celery (diced)

1 Yellow onion (diced)

3 cloves Garlic

 8 oz Mushrooms (diced)

1/2 tsp Oregano, ground

1 tsp Thyme, ground

1 cup vegetable broth
1 Thyme, Fresh



3 sweet potatoes (peeled and chopped)

1 head cauliflower (chopped and destemmed)

6 tsp of butter (Olive Oil would work here too if you’re vegan)

3 Tbs. nutritional yeast

1 Tbs. Dijon Mustard

Salt and pepper to taste



  1. Preheat oven to 350 degrees.
  2. Cook lentils according to package instructions.
  3. While lentils are cooking, sautee carrots, celery, mushrooms and onion until onions are translucent. Then add garlic and seasonings. Stir frequently.
  4. Once lentils are cooked, add them to the vegetable mix, as well as the vegetable broth. Let simmer for a few minutes to let flavors mesh.
  5. In a large pot, boil water and add sweet potatoes. Let them cook for 5-7 minutes until they begin to get fork tender. Then add the chopped cauliflower (add this later because they cook quicker). Once both are fork tender, drain and place in a food processor or blender, along with 6 tsp of melted butter, dijon mustard and nutritional yeast. Blend until creamy. ** You are basically making mashed potatoes here, and you may wish to add milk or cream. I did not because I needed this to fit my meal plan.
  6. In a large baking dish (sprayed with cooking spray) pour the lentil and vegetable mix and with a spatula, spread even. Then top with the cauliflower/sweet potato mash, and spread evenly with a spatula.
  7. Place in the oven for 15 minutes, or until lightly golden.



If you are making this 21 Day Fix, 21 Day Fix Extreme or 80 Day Obsession approved, you will divide the entire thing into 6 servings. A serving would be 1 green container (veggies and cauliflower), 1 red container (lentils), 1 yellow container (sweet potato) and 1 tsp (butter or olive oil).
