Main Ingredients and Their Quantities

Below is the full ingredient list for 2 large double-patty burgers (serves two people). Each ingredient is carefully chosen for both flavor and texture balance.

For the Burger Patties

• 1 pound (450g) ground beef (80/20 lean-to-fat ratio): The key to a juicy burger is fat content. An 80/20 mix ensures rich flavor and tenderness while maintaining structure.
• ½ teaspoon salt: Enhances the natural flavor of beef. Avoid oversalting before cooking; it can draw out moisture.
• ¼ teaspoon freshly ground black pepper: Adds depth and a hint of spice to the meat.
• ¼ teaspoon garlic powder: Provides a subtle umami note that complements onions perfectly.

For the Onion Wraps

• 2 large yellow onions: These serve as the “bun.” When roasted, yellow onions develop a natural caramel sweetness and a sturdy yet tender texture.
• 1 tablespoon olive oil: Helps the onions roast evenly and prevents sticking.
• ¼ teaspoon salt: Enhances caramelization and balances sweetness.

For the Cheese Layer

• 4 slices American cheese or cheddar cheese: Melts smoothly between patties, creating that signature Flying Dutchman gooey texture.
• Optional: 1 teaspoon Dijon mustard or a smear of mayonnaise between layers for extra tang.

Optional Garnishes

• 1 teaspoon sugar-free ketchup or burger sauce (for keto-friendly flavor)
• 1 tablespoon dill pickles, chopped (adds crunch and acid contrast)
• Fresh parsley or chives for garnish

Total Yield

This recipe makes 2 hearty double-patty burgers (each wrapped in onion layers). Total yield is approximately 2 servings — perfect for a satisfying dinner or a high-protein meal prep option.

How to Prepare the Onion Wrapped Flying Dutchman Burger

Step 1: Prepare the Onion “Buns”

Begin by preheating your oven to 400°F (200°C). Peel the large onions and slice them crosswise into thick 1-inch rounds. Carefully separate the outermost 2–3 rings of each slice, which will serve as your “buns.” Save the smaller inner rings for later — they can be sautéed for topping or added to the beef mixture.

Line a baking sheet with parchment paper and arrange the onion rings in pairs (two per burger). Drizzle olive oil lightly over them and sprinkle with salt. Roast in the preheated oven for 20 minutes, flipping halfway through. The goal is to achieve tender, slightly caramelized onions that still hold their shape. Once done, set them aside to cool slightly.

Step 2: Form and Season the Patties

While the onions roast, divide the ground beef into four equal portions (about 4 ounces each). Gently form each portion into a flat, round patty slightly larger than the onion rings — they will shrink slightly during cooking. Season both sides with salt, pepper, and garlic powder.

Avoid overworking the meat, as compacting it too much can result in dense burgers. Press a small indentation into the center of each patty with your thumb; this ensures even cooking and prevents puffing in the middle.

Step 3: Cook the Burger Patties

Heat a large cast-iron skillet or nonstick pan over medium-high heat. Once hot, add the patties (no oil needed if using a good-quality nonstick surface). Sear for 3 minutes per side for medium doneness, or slightly longer if you prefer a well-cooked burger.

Place a slice of cheese on each patty immediately after flipping, allowing it to melt as the second side cooks. Once cooked, remove patties to a plate and let them rest for two minutes. Resting helps redistribute juices and keeps the burger moist.

Step 4: Assemble the Onion Wrapped Burgers

To build the Flying Dutchman burger, take two onion “bun” halves and place one on the plate as the base. Add a cooked patty topped with cheese, followed by another cheese-covered patty. Finish by gently placing the second roasted onion “bun” on top, pressing lightly to help everything hold together.

If desired, you can add a thin layer of Dijon mustard or sugar-free ketchup between patties for extra flavor. Garnish with chopped pickles or parsley for a finishing touch. The result should be a stacked, cheesy, glossy burger wrapped in sweet, caramelized onion layers — rich, aromatic, and ready to devour.

Step 5: Serving Suggestions

Serve your Onion Wrapped Flying Dutchman Burgers immediately while hot and juicy. Pair with zucchini fries, cauliflower mash, or a crisp keto coleslaw for a balanced low-carb meal. You can also add a side of roasted vegetables or a simple garden salad to round out the dish.

If preparing in advance, store the patties and onions separately to maintain texture. Reheat in a skillet or oven before assembling to preserve crispness and flavor.

Healthy Habits: Making This Burger Nutritious and Balanced

Despite being indulgent and savory, this burger aligns with health-conscious eating habits. Using onion wraps instead of buns cuts out refined carbohydrates, making it suitable for low-carb, keto, and gluten-free diets. The high protein and moderate fat content promote satiety, meaning you stay full longer and avoid post-meal cravings.

Additionally, caramelized onions add natural sweetness without processed sugars, reducing the need for sugary condiments. Opting for grass-fed beef and quality cheese enhances nutritional value with more omega-3 fats and conjugated linoleic acid (CLA). Pairing the burger with high-fiber vegetables balances the meal and supports digestion.

Mindful portioning is another healthy habit — while this recipe serves two, you can easily make smaller patties for lighter meals or appetizers. Drinking water or green tea with your burger helps manage sodium levels and aids digestion, making this dish both delicious and smartly balanced.

Variations of the Onion Wrapped Flying Dutchman Burger

1. Spicy Jalapeño Flying Dutchman Burger

For spice lovers, add sliced jalapeños or a dash of hot sauce to the beef mixture before forming patties. This variation introduces heat that contrasts beautifully with the sweetness of roasted onions. You can also melt pepper jack cheese instead of American or cheddar to enhance the flavor profile. A thin layer of chipotle mayo brings smoky depth to each bite.

In this version, the heat from the jalapeños balances the natural sugars of the onions, creating a bold, crave-worthy burger that excites the palate. Perfect for summer cookouts or game-night meals, this spicy twist delivers big flavor while keeping carbs minimal. Serve with avocado slices or a light cucumber salad to cool the spice.

2. Mushroom and Swiss Onion Wrapped Burger

This earthy variation replaces cheddar with Swiss cheese and incorporates sautéed mushrooms layered between the patties. The mushrooms bring umami depth and a tender texture that pairs harmoniously with the caramelized onions. A touch of Worcestershire sauce or soy sauce during cooking enhances richness.

The Mushroom and Swiss version is ideal for those who appreciate comfort food flavors with gourmet appeal. The melted Swiss cheese ties everything together with smooth creaminess, while mushrooms add fiber and minerals like selenium. This variation also reheats beautifully, making it excellent for meal prepping lunches.

3. Barbecue Bacon Flying Dutchman

For a smoky, indulgent version, layer crispy bacon strips and sugar-free barbecue sauce between the cheese-covered patties. The salty, smoky bacon enhances the burger’s flavor intensity, while the sauce provides tangy sweetness. Use smoked gouda or mozzarella cheese to tie the flavors together.

This variation is perfect for backyard grilling or casual weekend dinners. While slightly higher in calories, it’s still low in carbs and incredibly satisfying. Pair it with grilled asparagus or roasted broccoli to balance richness with fresh greens. It’s a crowd-pleaser that turns ordinary burgers into a restaurant-quality feast.

4. Veggie-Friendly Cauliflower “Flying Dutchman”

For a vegetarian-friendly alternative, replace the beef patties with cauliflower or black bean patties. Keep the onion wraps and cheese for texture consistency. Adding smoked paprika and cumin to the patties enhances their savory flavor while keeping the burger hearty and satisfying.

This version delivers a lighter option with more fiber and plant-based nutrients. Perfect for vegetarians or anyone reducing red meat intake, it retains the signature Flying Dutchman structure while catering to diverse dietary preferences. Serve with a dollop of Greek yogurt sauce or tzatziki for freshness.
