French Onion Grilled Cheese Sandwich

I simply can not put into words how delicious this grilled cheese is!


Servings: 3 sandwiches

  • 1 large Yellow Onion, thinly sliced
  • 8 oz. Mushrooms, about 1 ½ cups, thinly sliced
  • 4 tbsp. Butter
  • 1 tbsp. Fresh Thyme, chopped
  • (Optional) 2 Garlic Cloves, minced
  • 1 tsp. Salt
  • ½ tsp. Black Pepper
  • 6 slices Sourdough Bread
  • 6 oz Organic Valley Raw Sharp Cheddar Slices


  1. In a large skillet over medium-high heat, add 2 tablespoons butter.
  2. Once melted, add the thinly sliced onions. Season with the salt and black pepper.
  3. Cover and cook for 5-6 minutes, until softened.
  4. Stir the onions as you add ¼ cup water to de-glaze the pan. Reduce heat to medium and continue the cooking process until the onions are deeply caramelized, about 10-15 more minutes.
  5. Increase heat to medium high heat again. Add the thinly sliced mushrooms, (optional) minced garlic, and chopped thyme. Saute until the mushrooms are tender.
  6. On a slice of sourdough bread, add 1-2 slices of the Raw Cheddar Cheese, followed by 1/3rd of the caramelized onions and mushrooms, another 1-2 slices of cheese, and sandwich with a second slice of bread. Repeat with remaining sandwiches.
  7. Butter the outside of the sandwiches, then place on a skillet over medium heat to cook 2-3 minutes, until golden on the outside and cheese is melted. Cover with a pan lid to help the cheese melt. Enjoy!
