Roasted sweet potato cubes and smoky, garlicky ground beef in a 9 x 13-inch dish, covered with cottage cheese whisked into eggs and finished with sharp cheddar.
The cottage cheese layer sets in the oven rather than staying loose, which is what makes this a casserole with a top rather than a mince with cheese on it.
Why This Recipe Works
- Cottage cheese whisked with two eggs sets into a soft, savoury custard in a 20-to-25-minute bake. That is why the eggs are there — without them the cottage cheese would weep and slide rather than hold a cut edge.
- The sweet potatoes are roasted first and only to just tender. Raw cubes stirred straight into a casserole never catch up, and fully soft ones lose their shape entirely under the topping.
- Smoked paprika against sweet potato is the pairing doing the real work. A teaspoon is enough to read as smoke rather than as spice, and it stops the dish tipping sweet.
- Lean ground beef, then drained. A pound of ordinary mince would leave enough rendered fat to pool under a custard topping and split it.
- Sharp cheddar rather than mild, and only a cup. It is a finishing layer over a mixture that is already rich; mild cheddar disappears into the cottage cheese entirely.
Two Pans, One Twenty Minutes
Step 3 begins with the word meanwhile, and that word is the whole shape of this recipe. The sweet potatoes take 18 to 20 minutes in the oven; the beef takes about the same on the hob. Run them in sequence and you have added twenty minutes to a weeknight for nothing.
In the oven, on a sheet pan
- Straight away
Oven to 400°F, the 9 x 13-inch dish greased, and the cubed sweet potatoes tossed with half the olive oil and spread on a sheet pan.
- 18 to 20 minutes
Roast until just tender. Just tender is deliberate — they get another 20 to 25 minutes in the casserole and fully soft cubes collapse into purée.
On the hob, in a large skillet
- As the tray goes in
The remaining oil, then the ground beef and diced onion, cooked until the beef is browned and no pink remains. Drain the excess fat.
- The last 30 seconds
Garlic, smoked paprika, thyme, salt and pepper into the hot pan. Thirty seconds, not longer — the paprika is there to bloom, not to toast.
Where they meet, at step 6
Roasted cubes and seasoned beef go into the greased dish together. Only then is the cottage cheese and egg mixture spooned over and gently spread, cheddar scattered on top, and the whole thing baked 20 to 25 minutes.
Ingredient Notes
- Sweet potatoes, 1/2-inch cubes
- A pound and a half, cut to half an inch. This is the recipe's only starch — there is no pasta, rice or potato tot in it, and adding one would change what the 20-to-25-minute bake is timed for.
- Cottage cheese
- A full cup, whisked with the eggs rather than dolloped. Small-curd or large-curd both set; what matters is that it is whisked until the eggs are properly through it.
- Lean ground beef
- Lean, and drained anyway at step 3. The topping is an egg custard and rendered fat underneath it is what makes a custard break.
- Smoked paprika
- Smoked rather than sweet or hot. It is doing the smoke-against-sweet-potato job on its own here, so the substitution is not a neutral one.
- Sharp cheddar, divided
- The line says divided and the method uses it once, at step 7. Treat the whole cup as the topping unless you want a second cheese layer in the middle.
How to Make It
Heat the oven and grease the dish
Heat the oven to 400°F and lightly grease a 9 x 13-inch baking dish.
Roast the sweet potatoes
Toss the sweet potatoes with half the olive oil and spread them on a sheet pan. Roast for 18 to 20 minutes, until just tender.
Brown the beef and onion
Meanwhile, heat the remaining oil in a large skillet. Cook the ground beef and onion until the beef is browned and no pink remains. Drain excess fat.
Bloom the seasonings
Stir in the garlic, smoked paprika, thyme, salt and pepper and cook for 30 seconds.
Whisk the topping
Whisk the cottage cheese and eggs together in a bowl.
Layer the dish
Combine the roasted sweet potatoes and beef mixture in the baking dish. Spoon the cottage-cheese mixture over the top and gently spread it.
Cheese and bake
Sprinkle with the cheddar cheese and bake for 20 to 25 minutes, until hot throughout and the cheese is melted.
Rest, then finish
Rest for 5 minutes and finish with parsley if using.
Success Tips
- Start the sheet pan and the skillet within a minute of each other — the recipe is built on them running together.
- Pull the sweet potatoes at just tender; the casserole finishes them.
- Whisk the cottage cheese and eggs until no separate egg streaks remain.
- Spread the topping gently so it stays a layer rather than sinking into the beef.
- Give it the full five minutes of rest before cutting or the custard will not hold an edge.
Serving Ideas
It needs nothing starchy alongside. A sharp green salad or quick-dressed cabbage is the useful contrast to a rich, sweet-edged dish.
Storage and Reheating
Refrigerate
Refrigerate leftovers in an airtight container for up to 4 days. Cut portions hold their layers better than a scooped spoonful.
Freeze
Freeze cooled portions for up to 2 months. The custard top firms slightly on thawing; the texture is best if thawed overnight in the fridge rather than from frozen.
Reheat
Reheat covered at 350°F for 15 to 20 minutes, until hot through. A microwave works for a single portion but softens the cheddar crust.
Frequently Asked Questions
The topping was watery.
Almost always undrained beef. Step 3 says to drain the excess fat, and rendered fat sitting under an egg-and-cottage-cheese layer keeps it from setting cleanly.
Can I skip roasting and put the sweet potato in raw?
No. The casserole bake is 20 to 25 minutes and half-inch raw cubes are not tender in that time. The roast is what makes the bake short.
Should I blend the cottage cheese smooth?
You can, and it gives a more uniform top. Whisked by hand is what the recipe asks for and it sets just as firmly — the curds simply stay visible.
Can I add rice or tater tots to bulk it out?
Not without making it a different dish. Sweet potato is the defining starch here, and it is what the seasoning and the bake time are balanced around.
