There is nothing quite like a steaming dish of classic Shepherd’s Pie on a chilly evening. Rich, savory beef gravy packed with tender veggies, all tucked under a golden, buttery blanket of mashed potatoes—it’s the ultimate comfort meal.
However, traditional recipes are often heavy on fats and refined starches while falling short on the protein needed to keep you full.
For the grand finale (Day 5) of our High-Protein 5-Day Comfort Food Series, we’re giving this household staple a major nutritional upgrade. By making a few intentional, chef-approved ingredient swaps, we’ve created an ultra-creamy, high-protein Shepherd’s Pie that delivers a massive 30 grams of protein per serving without sacrificing an ounce of rich, nostalgic flavor.
Why This High-Protein Version Works
1. Bone Broth vs. Regular Stock: The Protein Game-Changer
You’ll notice this recipe specifically calls for beef bone broth rather than standard beef stock or broth. This choice is 100% intentional. Standard beef stock is made by quickly simmering meat and vegetables, yielding about 1–2 grams of protein per cup. Beef bone broth, on the other hand, is slow-simmered for hours to extract natural collagen, gelatin, and amino acids directly from the bones.
Using beef bone broth adds up to 9 grams of protein per cup straight into your gravy base while giving the sauce a luxuriously rich body that coats every bite of beef and vegetables.
2. The Secret to Creamy, High-Protein Mashed Potatoes
If you’ve ever tried adding protein powder or extra Greek yogurt to mashed potatoes, you know the texture can quickly turn chalky or tangy. The secret here is blending 4% cottage cheese directly with half-and-half in a high-speed blender before mixing it into the hot potatoes.
Blending completely breaks down the curds into a silky liquid. Combined with a touch of butter and plain Greek yogurt, it creates a rich, decadent potato topping that tastes like it came from a steakhouse, while secretly packing over 35 grams of protein into the topping alone!
Custom Substitutions & Dietary Swaps
This recipe is extremely forgiving and easy to customize based on your personal macro goals or dietary preferences:
- Protein / Meat Swaps: Traditional Shepherd’s Pie uses lamb, while “Cottage Pie” uses beef. You can easily use 2 lbs of lean ground lamb, ground turkey, or ground chicken. If you use extra-lean poultry (like 93/7 ground turkey), add an extra splash of bone broth to keep the meat juicy.
- Lowering the Fat: We used 85/15 ground beef and 4% whole-milk cottage cheese for maximum richness. To cut down total calories and fat, swap in 90/10 or 93/7 ground beef and use fat-free or 2% low-fat cottage cheese.
- Dairy-Free Option: Use plant-based butter, unsweetened almond or oat milk, and a dairy-free cream cheese alternative blended into the potatoes.
Recommended Kitchen Equipment
- High-Speed Blender: Essential for whipping the cottage cheese and half-and-half into a silky-smooth liquid.
- Large Cast-Iron Skillet or Dutch Oven: Perfect for browning the beef, simmering the gravy, and baking everything in a single pan.
- Large Potato Masher or Ricer: Ensures your Russet potatoes are light and fluffy before folding in the wet ingredients.

Ingredients
The Beef & Veggie Filling
- 2 lbs 85/15 ground beef (or ground turkey/lamb/chicken)
- 1 tbsp avocado oil
- 1 medium yellow onion, finely chopped
- 4 stalks celery, chopped
- 4 medium carrots, diced
- 6 cloves garlic, minced
- 1 small can (6 oz) tomato paste (or 4 tbsp)
- 2 cups beef bone broth
- 1 can (1 ¾ cups drained) organic sweet peas
- 1 tbsp cornstarch (dissolved in ¼ cup cold water)
- Seasoning Blend: 3 tsp salt (divided), 1 tbsp dried parsley, 1 tsp dried thyme, ¼ tsp cayenne pepper, fresh cracked black pepper to taste
The High-Protein Potato Topping
- 7 medium Russet potatoes, peeled and quartered (~2.5 lbs)
- ½ cup butter, softened
- 1 cup 4% cottage cheese (or low-fat)
- ½ cup half-and-half
- ⅓ cup plain Greek yogurt
- ½ cup sharp cheddar jack cheese, shredded
Step-by-Step Instructions
Step 1: Boil the Potatoes
Place the peeled, quartered Russet potatoes into a large pot of cold, salted water. Bring to a rolling boil over medium-high heat and cook for 15–20 minutes, or until fork-tender. Drain thoroughly and return them to the warm pot.
Step 2: Brown the Meat
While the potatoes boil, heat avocado oil in a large oven-safe skillet or Dutch oven over medium-high heat. Add the ground beef, season with 2 tsp salt and black pepper, and cook for 6–8 minutes until fully browned. Transfer cooked beef to a plate, leaving the excess drippings in the skillet.
Step 3: Build the Aromatic Base
Add chopped onion, celery, and carrots directly into the same skillet. Sauté for 5–7 minutes until tender. Stir in the minced garlic and tomato paste, cooking for another 2 minutes to caramelize the paste and deepen the flavor.
Step 4: Simmer the Bone Broth Gravy
Return the browned beef to the skillet. Pour in the beef bone broth, remaining 1 tsp salt, dried parsley, thyme, and cayenne pepper. Bring to a simmer. Pour in the cornstarch slurry and stir constantly for 2–3 minutes until the gravy thickens to a glossy finish. Fold in the drained sweet peas and remove from heat.
Step 5: Blend & Whip the Mashed Potatoes
Add the cottage cheese and half-and-half to a high-speed blender. Blend on high for 30–45 seconds until completely liquid and silky smooth with no visible curds.
Mash the drained potatoes, then fold in softened butter, the blended cottage cheese mixture, and Greek yogurt. Season with salt to taste and whip until fluffy and smooth.
Step 6: Assemble, Bake & Broil
Preheat oven to 400°F (200°C).
If using an oven-safe skillet, spread the potato mixture evenly over the beef filling. (If using a standard pan, transfer filling to a 9×13 baking dish first, then top with potatoes). Smooth the top with a spatula and sprinkle shredded cheddar jack cheese evenly over the potatoes.
Bake for 20 minutes, then turn on the broiler for 2–3 minutes until the cheese is melted, bubbly, and golden brown. Let rest for 10 minutes before slicing into 10 portions.
Meal Prep, Storage & Reheating
- Refrigerator Storage: Allow the pie to cool completely before transferring to airtight meal prep containers. Store in the fridge for up to 5 days.
- Freezer Storage: You can freeze individual portions or the entire baked dish! Wrap tightly in foil and plastic wrap and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
- Best Reheating Method: Reheat single portions in the microwave for 1.5 to 2 minutes, or cover the dish with foil and heat in a 350°F oven for 15–20 minutes until hot throughout.
Frequently Asked Questions (FAQs)
Q: Why use Russet potatoes instead of Yukon Gold?
A: Russet potatoes are high in starch and low in moisture, making them ideal for absorbing butter and blended dairy without turning gummy or watery.
Q: Will the gravy turn watery when reheated for meal prep?
A: No! The cornstarch slurry combined with the natural gelatin in the beef bone broth binds the liquid together, ensuring your gravy stays thick and rich all week.
