If you’re looking to elevate your sandwich game, these Guinness-Marinated Bison Steak Sandwiches deliver bold flavors and juicy texture in every bite.

Ingredients

For the Marinade:

• 1 cup Guinness stout beer
• 3 tablespoons soy sauce
• 2 tablespoons molasses
• 2 cloves garlic, minced
• 1 tablespoon Dijon mustard
• 1 teaspoon black pepper

For the Sandwiches:

• 1½ pounds bison steak
• 4 sandwich rolls or ciabatta buns
• 1 large onion, thinly sliced
• 1 tablespoon olive oil
• Lettuce leaves
• Sliced tomatoes
• Prepared horseradish mayonnaise or your favorite sauce

Instructions

Begin by preparing the marinade. In a large bowl, whisk together the Guinness stout, soy sauce, molasses, garlic, Dijon mustard and black pepper until well combined.

Place the bison steak in a resealable bag or shallow dish and pour the marinade over the meat. Cover and refrigerate for at least 4 hours, preferably overnight, allowing the flavors to penetrate the steak.

Remove the steak from the refrigerator about 30 minutes before cooking. Meanwhile, heat olive oil in a skillet over medium heat and cook the sliced onions until soft and caramelized, about 15 to 20 minutes. Set aside.

Preheat a grill or grill pan to medium-high heat. Remove the bison steak from the marinade and pat dry lightly. Grill the steak for about 4 to 5 minutes per side for medium-rare, depending on thickness. Avoid overcooking, as bison is leaner than beef and can dry out quickly.

Transfer the cooked steak to a cutting board and let it rest for 5 to 10 minutes before slicing thinly against the grain.

Toast the sandwich rolls lightly. Spread horseradish mayonnaise on both sides of each roll. Layer with lettuce, sliced tomatoes, grilled bison steak and caramelized onions.

Serving Suggestions

Serve the sandwiches hot with crispy fries, sweet potato wedges, coleslaw or a fresh green salad. The rich flavors of the Guinness marinade pair beautifully with roasted vegetables and grilled corn.
