This lentil shepherd’s pie with cottage cheese mash has 38 g of protein per serving and takes 100 minutes, about 35 of them hands-on. The protein comes from lentils, cottage cheese and Parmesan, not powder, so it tastes like the real thing.
Across the whole dish that’s about 50 g from the lentils, 57 g from the cottage cheese, 14 g from the Parmesan, and roughly 30 g from the potatoes, peas and mushrooms. Split four ways, one serving is about 550 g of food. It eats like a full dinner.
The cottage cheese goes right into the potatoes. You get a tangier, creamier mash than plain potato gives you, and it browns well in a hot oven. It’s what I make when a Duluth January won’t quit.
One trade-off: this isn’t a 30-minute dinner. Most of the time is simmering and baking, so you can do other things while it cooks.
Why You’ll Love This Recipe

- Each serving is about 550 g, a full dinner plate
- No protein powder, so the mash tastes like mash
- Reheats in single portions for lunches all week
Ingredient Notes
- Brown or green lentils: Use dry lentils that hold their shape. Red lentils break down into a paste, so skip them here.
- Cottage cheese: Small-curd 2% or 4% both work. Drain it well, and check the label because protein varies by brand.
- Parmesan: Traditional Parmesan uses animal rennet. For a strictly vegetarian pie, use a hard cheese labeled vegetarian.
- Soy sauce: It adds salt and savory depth to the filling. Use gluten-free tamari if you need to avoid wheat.
- Yukon Gold potatoes: They mash creamy and hold less water than russets. Russets work but give a drier, fluffier mash.
Lentil Shepherd's Pie: Cottage Cheese Mash, 38g Protein
Ingredients
Method
- Dice the onion, carrots and celery, chop the mushrooms to pea size, mince the garlic, and rinse the lentils in a fine-mesh sieve.
- Set a 30 cm / 12-inch deep skillet or sauté pan over medium heat and add the olive oil. Cook the onion, carrots and celery for 6 to 7 minutes until the onion is soft and translucent. Add the mushrooms and cook 5 to 6 minutes until their liquid evaporates and they brown at the edges. Stir in the garlic, tomato paste, thyme, paprika and pepper for 1 minute until the paste darkens.
- Add the lentils, broth, soy sauce and bay leaf. Bring to a boil, reduce to low, cover, and simmer for 25 minutes, stirring every 8 minutes or so, until the lentils are tender but still hold their shape.
- About 10 minutes into the lentil simmer, tip the cottage cheese into a fine-mesh sieve set over a bowl and let it drain for at least 10 minutes. Put the potatoes in a 3-quart / 2.8 L saucepan, cover with cold water, add 1 tsp salt, and bring to a boil. Simmer 15 to 18 minutes until a knife slides into a chunk with no resistance.
- When the lentils have simmered 25 minutes, stir in the peas, remove the lid, and cook 3 minutes until the filling is thick and no liquid pools when you drag a spoon through it. Remove the bay leaf and spread the filling in a 23 x 33 cm / 9 x 13-inch baking dish. Heat the oven to 200 C / 400 F with a rack in the middle.
- Drain the potatoes and return them to the hot pot for 1 minute to steam dry. Mash with the butter until smooth, then stir in the drained cottage cheese, Parmesan, 1/4 tsp salt and the pepper. Don't skip the draining, because wet cottage cheese makes a loose mash that slides into the filling and won't brown.
- Spread the mash over the filling all the way to the edges and rake the top with a fork. Bake for 25 minutes until the edges bubble and the ridges have golden spots. Rest 10 minutes before cutting into 4 portions.
Notes
- Drain the cottage cheese for at least 10 minutes so the mash browns instead of weeping.
- Rest the pie 10 minutes after baking so the filling sets and squares hold together.
- No protein powder is used anywhere, so there is no powder-free swap to make.
- Use brown or green lentils, since red lentils break down into a paste.
- Cottage cheese protein varies by brand, so check the label if you track grams.
Tips for Success
- Chop the mushrooms to pea size so they melt into the filling and add depth without chewy pieces.
- Salt the potato water with 1 tsp, since the mash itself only gets 1/4 tsp and the cottage cheese is already salty.
- Blend the drained cottage cheese for 20 seconds first if you want a smooth mash with no visible curds.
- Stop cooking the filling when a spoon dragged across the skillet leaves a trail that closes slowly.
- Rake the mash with a fork before baking so the ridges catch heat and brown.
Variations
- Swap 200 g of the potatoes for cauliflower florets boiled in the same pot for a lighter mash that browns just as well.
- Add 120 ml of red wine to the vegetables before the broth and let it cook down for a deeper, tangier filling.
- Stir 1 tsp chili powder and 1 tsp cumin into the filling and top the mash with pepper jack for a Tex-Mex version.
Storage and Reheating
Lentil shepherd’s pie keeps in the fridge for 4 to 5 days in a covered dish or airtight containers. Get it into the fridge within 2 hours of baking.
Reheat a single portion in a small baking dish, covered with foil, at 175 C / 350 F for 20 to 25 minutes until bubbling at the edges. A whole dish needs 30 to 35 minutes. In the microwave, a portion takes 2 to 3 minutes at 70% power, but the top won’t brown.
Freeze portions for up to 3 months. Thaw overnight in the fridge and reheat the same way. The mash turns slightly grainier after freezing because of the cottage cheese, but the flavor stays the same.
Serving Suggestions
Cut the pie into squares after its 10-minute rest so the filling holds its shape on the plate. One quarter of the dish is about 550 g, which fills a dinner plate on its own.
Add something sharp and green on the side. Arugula tossed with lemon juice and olive oil, a cabbage slaw with cider vinegar, or steamed green beans all cut through the creamy mash.
A spoonful of plain Greek yogurt on top works like sour cream and adds tang. Those grams aren’t counted in the 38 g per serving.
FAQ
Why is my cottage cheese mash watery on top of the lentil shepherd’s pie?
A watery mash usually means the cottage cheese wasn’t drained or the potatoes went into the bowl wet. Drain the curds in a sieve for at least 10 minutes, and steam the boiled potatoes dry in the hot pot for 1 minute. A filling that’s still soupy can also swallow the mash, so cook it until it’s thick.
Can I use red lentils instead of brown in lentil shepherd’s pie?
You can, but the texture changes. Red lentils break down in about 15 minutes and give a smooth, dal-like filling instead of distinct lentils. Cut the broth to 500 ml and the simmer to 15 minutes if you try it. Brown or green lentils give the classic textured filling and hold their shape under the mash.
Can I freeze lentil shepherd’s pie that has a cottage cheese mash?
Yes, for up to 3 months. Cool it completely, portion it into freezer-safe containers, and thaw overnight in the fridge. The cottage cheese gives the mash a slightly grainier feel after thawing, but the taste holds. Reheat covered at 175 C / 350 F for 20 to 25 minutes.
What vegetable goes best next to lentil shepherd’s pie?
Something sharp and green works best, because the mash is creamy and rich. Arugula with lemon vinaigrette, quick-pickled red onions, or broccoli roasted on a sheet pan alongside the pie at 200 C / 400 F all work. Skip bread, since the pie already has 600 g of potato across the dish.
Is lentil shepherd’s pie with cottage cheese mash gluten free?
Not as written, because standard soy sauce contains wheat. Swap in tamari labeled gluten free and check your vegetable broth label. Lentils, potatoes, cottage cheese and Parmesan are naturally gluten free, though some cottage cheese brands add thickeners, so read that label too.
What is the difference between shepherd’s pie and cottage pie?
Shepherd’s pie is traditionally made with lamb and cottage pie with beef, both under a potato topping. This lentil version has no meat, so it’s a meat-free take on either one. The cottage cheese here is a topping ingredient and has nothing to do with the name cottage pie.
