Cottage Cheese Onion Ring Smash Burger — The Viral Stack You Need to Try

The cottage cheese onion ring smash burger is the mashup nobody asked for but everyone needs. It takes the viral cottage cheese onion ring — crispy, high-protein, low-carb — and turns it into the bun for the juiciest smash burger you will ever make at home. No bread. No deep-frying. Just 30 minutes and a cast-iron skillet.

I first made this on a Tuesday night when I had ground beef, a big yellow onion, and a tub of cottage cheese staring at me from the fridge. What came out stopped everyone at the table mid-sentence. That crispy onion ring holds up better than any brioche bun, and the cottage cheese binds it so cleanly you would never guess it was in there.

This recipe combines two of the most searched recipes on this site — the cottage cheese onion rings and the smash burger technique — into one complete dinner that is genuinely easier than it looks.

Why This Combination Works

The smash burger needs high heat and thin patties. The cottage cheese onion ring needs high heat and a flat surface. Both cook in the same cast-iron skillet, one right after the other, which means you are only dirtying one pan and the timing lines up perfectly.

Nutritionally, this stack is a standout. Cottage cheese adds protein to the onion ring binder, the beef patty adds another 20 to 25 grams per serving, and the whole thing comes in well under 500 calories — with zero bread.

Ingredients — Serves 2

For the Cottage Cheese Onion Rings (the ‘bun’)

• 1 large yellow onion
• 1/2 cup full-fat cottage cheese
• 2 tablespoons grated Parmesan cheese
• 1 egg
• Salt and black pepper to taste

For the Smash Burger Patties

• 3/4 lb ground beef, 80/20
• Salt and black pepper
• 2 slices American cheese or cheddar
• 1 tablespoon neutral oil or butter

Optional Toppings

• Pickles, lettuce, sliced tomato
• Burger sauce: 2 tbsp mayo + 1 tbsp ketchup + 1 tsp pickle juice

How to Make the Cottage Cheese Onion Ring Smash Burger

Step 1 — Make the cottage cheese onion rings

1. Preheat oven to 400°F. Line a baking sheet with parchment.
2. Slice the onion into 1-inch thick rounds. Separate into rings. Select 4 large outer rings — these will be your ‘buns.’
3. In a bowl, mix cottage cheese, Parmesan, egg, salt and pepper until smooth.
4. Place rings on the baking sheet. Spoon the cottage cheese mixture into each ring, pressing it flush to the edges.
5. Bake for 20 to 25 minutes until golden, firm, and slightly crispy at the edges.
6. Let cool on the tray for 5 minutes — they firm up as they cool.

Step 2 — Make the smash burger patties

• Divide the ground beef into 4 equal balls, about 3 oz each.
• Heat a cast-iron skillet over high heat until smoking. Add oil.
• Place two beef balls in the pan. Immediately smash flat with a metal spatula and a piece of parchment on top. Press hard — you want thin, lacy-edged patties.
• Season with salt and pepper. Cook 60 to 90 seconds until the edges are deeply browned and crispy.
• Flip. Immediately add cheese to one patty. Stack the second patty on top. Cook 30 seconds more.
• Repeat with the remaining two balls.

Step 3 — Assemble

1. Place one cottage cheese onion ring flat side down on the plate.
2. Add toppings and burger sauce if using.
3. Stack the double smash patty on top.
4. Top with the second cottage cheese onion ring, pressing gently.
5. Serve immediately while the cheese is melted and the rings are still crispy.

Tips for the Best Result

• Use full-fat cottage cheese: Low-fat versions release too much water and the ring won’t firm up properly.
• Parmesan is the binder: It melts and creates a crispy edge as it bakes. Do not skip it.
• Let the rings cool before assembling: They are fragile straight from the oven. Five minutes on the tray makes them sturdy enough to hold the burger.
• Get the skillet screaming hot: The Maillard crust on a smash burger only forms with intense, immediate heat. If your pan is not smoking before you add the beef, you are not ready.
• Press once, hard, and fast: Smash the patty within the first 10 seconds of contact with the pan. After that, the proteins start to set and pressing only squeezes out juice.

Variations

• Turkey version: Replace ground beef with 80/20 ground turkey. The smash technique works identically.
• Double stack: Use four rings and four patties for a full double decker version.
• Spicy version: Add a teaspoon of smoked paprika and half a teaspoon of cayenne to the beef balls before cooking.
• Sauce swap: Swap the burger sauce for Sonic Groovy Sauce — our copycat version works perfectly on this stack.

What to Serve With It

This burger is filling on its own, but if you want a side that keeps the low-carb theme going, air-fried zucchini sticks or a simple green slaw work well. For something more classic, serve it next to regular fries or sweet potato fries.
