1-First, roast the jalapeno peppers whole on the grill or under the broiler until they blacken on all sides. Place them in a brown paper bag, seal it, and let them sit for 5 minutes before peeling off the skin, removing the seeds and stems, then cutting each into halves to make 4 slices total. Set these aside for later. In a bowl, combine the ground beef, egg, ketchup, salt, garlic, and onions, mixing everything thoroughly while adding any extra seasonings you like.

2-Next, form 8 thin patties from the meat mixture. On 4 of the patties, add one slice of jalapeno and one slice of pepper jack cheese each, then top with the remaining patties and seal the edges tightly. Cook the burgers on the grill or your preferred method until fully done, creating that spicy, cheesy center everyone loves. For added tips, remember that roasting helps reduce bitterness and brings a smoky taste, while sealing edges keeps the cheese inside.

3-Preparation time is about 30 minutes, making this perfect for busy nights. If you’re adapting for vegan or vegetarian versions, use plant-based patties and cheese, adjusting cook times as needed. Preheat your grill or skillet to medium-high heat, and flip the patties once for even cooking to avoid dryness.
