Heat a large nonstick skillet over medium-low heat. Add the oil, shallots, apple, thyme and salt. Stir to combine. Cook, stirring occasionally until the apples and onions are tender, about 16 to 20 minutes. If the mixture starts to get too brown, add a splash of water, about 1 tablespoon at a time (I used 2 total). Transfer to a bowl and stir in the honey. Set aside.
Meanwhile make the burger patties, add all of the ingredients to a mixing bowl. Mix well to combine evenly. With wet hands, form the mixture into 4 equal patties.
Heat the large skillet over medium-high heat. Spray with oil and place the patties in the pan in an evenly layer. Cook for 3 minutes, then flip. Reduce the heat to medium-low and cover. Continue cooking until the burgers are cooked through, about 5 minutes then top with the gruyere cheese, cover until the cheese is melted, 1 minute more.
Remove from the pan and serve immediately topped with the apple and shallot mixture.
Notes
Sliced gruyere cheese or grated can be used. Or swap for cheddar, Swiss, etc.
I didn’t feel like these needed extra toppings but feel free to add whatever you like. As far as condiments, you can use little dijon and mayo if serving on a bun.
