French Onions

  • 1 tbsp olive oil
  • 1/4 cup vegetable broth
  • 1/4 cup red wine
  • 3 onions (red or white) sliced

For the Grilled Cheese

  • 8 slices whole grain bread
  • 1 cup shredded cheddar cheese
  • 4 sprigs fresh thyme

For the Garlic Butter

  • 5 tsp butter
  • 1 clove garlic
  • salt and pepper to taste


  • Prepare the onions. Heat olive oil in a large skillet over medium heat. Add onions and cook until transparent and fragrant, about 8 minutes. Add stock and let it simmer until it completely disappears. Pour wine and let it reduce. Remove from heat.
  • Prepare garlic butter. Combine 5 tsp of room temperature butter with one clove of minced garlic, and salt and pepper to taste.
  • Assemble the garlic bread grilled cheese sandwich. Top a slice of whole grain bread with around ¼ cup french onion and ¼ cup cheddar cheese. Cover with another slice of bread. Spread ½ tsp of garlic butter on the outer layer of both slices of bread (you'll use 1 tsp per sandwich). Repeat the process to create 4 sandwiches.
  • In a large skillet over medium heat melt the remaining 1 tsp of butter. Add the thyme sprigs and cook for 2 minutes or until fragrant. 
  • Place the sandwiches in the skillet and cook for 3 minutes per side or until golden brown.

  • Be sure pan is preheated to medium-high heat before adding grilled cheeses.
  • To make gluten free, just use a gluten free bread!
  • Serve with a side of veggies for a complete and healthy meal.
