Mushroom-Swiss Burgers with Dijon-Horseradish Sauce

Ingredients

3 pounds Lean Ground Beef

1/3 cup Beef non-stick grilling marinade

1 Tbl Steak Seasoning

2 Tbl unsalted butter

3 cups sliced mushrooms

1 tsp salt

1 tsp fresh ground black pepper

6 1-ounce slices Swiss Cheese

6 Hamburger Buns

1/4 cup Unsalted Butter, melted

1 1/2 cup Fresh Spinach Leaves

6 red Onion Slices

1 Recipe Dijon Horseradish Sauce

Instructions

Divide the ground beef into six equal parts and form burger patties, approximately 1-1/2” thick.

Prepare the grill: Brush the surface of the burgers with the no-stick marinade and sprinkle with the steak seasoning. Cook over direct high heat for 8-10 minutes.

While the burgers are cooking:

Heat the butter in a medium sauté pan over high heat. Place mushrooms, salt, and pepper in the hot butter and sauté mushrooms for 6-7 minutes, stirring occasionally. Drain excess liquid.

While they are still on the grill, top each burger with one slice of each cheese. Divide the mushrooms evenly and place them atop the cheese. Close the lid on the grill and cook just until the cheese melts.

Brush the hamburger buns with the melted butted and toast on the grill over medium direct heat for 2-3 minutes.

Spread the Dijon mustard sauce on both sides of the bun. Place a burger on each bun and top with the fresh spinach leaves and red onions.

Yield: 6 Hamburgers

This pairs perfectly with Sweet Potato Pancakes. It may be better than the pancakes themselves (and they’re great). But try this recipe on regular pancakes, waffles, and French toast.

Sweet Potato Pancakes

I ate my first sweet potato pancake during my only visit to Gatlinburg, Tennessee. My family, along with another couple and their young children rented a cabin in the mountains during spring break. I woke every morning and headed into town for breakfast. I would imagine Gatlinburg has more pancake houses per capita than any place on the planet. My problem is that I never found a good-tasting pancake until I happened across sweet potato pancakes at one of the pancake houses. We serve a version of this recipe at The Midtowner. The Cinnamon Cream Syrup is a must.

RSJ’s Smoked Yellowfin Tuna Dip

The smoked tuna dip at Harbor docks is, by far, the best in the area. Actually, it’s the best I have ever tasted. Over the years I have taken a few stabs at recreating a Harbor Dock’s version, but always come up short. After several failed attempts, and facing a cookbook deadline, I finally worked up a recipe for smoked crab dip, which is excellent, though my wife still prefers Harbor Docks smoked tuna dip.
