Ingredients

For the High-Protein Steak Patties

1 lb (450g) lean ground beef (90–93% lean)
½ cup low-fat cottage cheese (blended smooth)
1 large egg
¼ cup oat flour or whole wheat breadcrumbs
2 cloves garlic, minced
½ teaspoon salt
½ teaspoon black pepper
½ teaspoon dried thyme

For the French Onion Gravy

3 large yellow onions, thinly sliced
1 tablespoon olive oil
1 tablespoon butter
1 teaspoon sugar (optional, helps caramelization)
2 cups low-sodium beef broth
1 tablespoon Worcestershire sauce
1 tablespoon cornstarch (mixed with 2 tablespoons water)

For the Topping

¾ cup shredded Gruyère or Swiss cheese
Fresh parsley (optional garnish)

Step-by-Step Instructions

1. Make the Steak Patties

In a large bowl, combine ground beef, blended cottage cheese, egg, oat flour, garlic, salt, pepper, and thyme.

Mix gently until just combined. Form into 4 oval patties.

The cottage cheese adds moisture and extra protein while keeping the patties tender.

2. Sear the Patties

Heat a large skillet over medium-high heat. Add a small drizzle of oil if needed.

Sear patties for 3–4 minutes per side until browned. Remove and set aside (they will finish cooking in the gravy).

3. Caramelize the Onions

In the same skillet, add olive oil and butter.

Add sliced onions and a pinch of salt. Cook slowly over medium heat for 20–25 minutes, stirring occasionally, until deeply golden brown.

Sprinkle sugar if desired to enhance caramelization.

Proper caramelization is key — don’t rush this step.

4. Build the Gravy

Stir in Worcestershire sauce and beef broth. Bring to a simmer.

Return the patties to the skillet, nestling them into the onions.

Cover and simmer for 10–12 minutes until patties are fully cooked (internal temp 160°F / 71°C).

Stir in the cornstarch slurry and cook 2–3 more minutes until the gravy thickens.

5. Add the Cheese

Sprinkle shredded Gruyère or Swiss over each patty.

Cover the skillet and cook for 2–3 minutes until cheese melts beautifully over the top.

6. Serve

Garnish with parsley and serve hot with mashed potatoes, cauliflower mash, or roasted vegetables.
