Ingredients
4 slices hearty bread (rye, whole grain, or sourdough)
2 cups sliced mushrooms (cremini, baby bella, or mix)
1 small onion, thinly sliced
2 tbsp butter (divided)
1 tsp fresh thyme (or 1/2 tsp dried)
1/2 tsp garlic powder
Salt & pepper to taste
1 cup shredded gruyère, mozzarella, or provolone cheese
Optional: a splash of balsamic or white wine for the mushrooms
Instructions
In a skillet, melt 1 tbsp butter over medium heat. Add mushrooms, onions, thyme, garlic powder, salt, and pepper. Sauté for 8–10 mins until golden and soft. Add splash of balsamic if desired and cook 1 more minute.
Butter the outside of each bread slice.
On the unbuttered side, layer cheese, mushroom mix, and top with more cheese if you like it extra gooey.
Grill over medium heat until bread is golden and cheese is melted, 3–4 mins per side.
Let it sit for 1 minute before slicing (it’s tough, but worth it!).
