Bistro-Style Onion Havarti Burgers

Bistro-Style Onion Havarti Burgers layer juicy, soup-mix–seasoned beef with buttery caramelized onions and tender mushrooms for deep, sweet-savory flavor. Creamy Havarti melts over the patties, and a swipe of mayonnaise adds richness, making these ideal for a relaxed weeknight dinner or a casual weekend cookout.

  1. 1

    Heat a large skillet over medium heat. Set the hamburger bun halves, cut-sides down, in the hot skillet and toast until lightly browned, 2 to 3 minutes. Transfer the toasted buns to a plate.

  2. 2

    Preheat an outdoor grill to medium heat. Melt butter in a large saucepan over medium heat on the grill. Add the mushrooms and onions; season with salt and black pepper, then cook and stir until the mushrooms are lightly browned, about 20 minutes.

  3. 3

    Meanwhile, combine the ground beef and onion soup mix in a bowl with your hands. Shape the mixture into 6 hamburger patties.

  4. 4

    Lightly oil the grill grates. Grill the burgers for about 5 minutes, then flip and continue grilling to your preferred doneness. A meat thermometer inserted into the center of the patties should register 180 degrees F (82 degrees C).

  5. 5

    Take the burgers off the heat and let them rest for 5 minutes. Spread each bun with 1 tablespoon mayonnaise, place the burgers on the buns, and divide the mushrooms and onions over the burgers to serve.

How easyChef Pro scores recipes and products

easyChef Pro analyzes up to 41 nutrients using data sourced from USDA and other verified food databases. Its scoring method uses the nutrients relevant to nutrition quality, calorie density, processing level, and your selected health goal. Recipes and food products get a health score from 0 to 100, calculated using consistent rules instead of being estimated by AI. The same nutrition data, serving size and health goal will produce the same result.

The calculation evaluates nutrients, calorie density, processing level, and how well the food supports your selected health goal. Protein, fiber, vitamins, minerals and other beneficial nutrients can strengthen the score. High amounts of sodium, saturated fat, added sugar and other nutrients may lower it.

Your health goal also matters. easyChef Pro evaluates recipes and products across six health areas and adjusts their importance for your selected goal. This means the same food may be a better fit for one health goal than another.

For recipes, changing an ingredient, quantity or serving size changes the nutrition and may change the score. Remix the recipe in easyChef Pro to calculate fresh nutrition and scores for the version you actually make. Product scores are based on the nutrition and serving information associated with that specific product.
