How to cook deliciously - French Onion Soup Bites

1 . Stage

Generously grease a 24-cup mini muffin pan with cooking spray. In a large skillet over medium heat, heat oil and butter until butter is melted. Add onions; season with a generous pinch of salt and pepper. Cook, stirring often, until tender and caramelized, about 30 minutes.

2 . Stage

Stir in broth and vinegar. Bring to a simmer and cook, stirring occasionally, until liquid is almost completely reduced but onions are still a little wet, about 5 minutes; season with salt and pepper, if needed. Remove from heat.

3 . Stage

Preheat oven to 375°. Unroll 1 can of crescent roll dough. Cut along perforated line to make 2 pieces. Cut each piece lengthwise down the center to create 4 large rectangles (there should be a seam to guide you here). Cut each rectangle into 3 pieces. Press pieces into muffin cups, stretching as needed to completely cover the sides. Repeat with remaining can.

4 . Stage

Spoon 1 tablespoon onion mixture into each cup. Sprinkle with cheese.

5 . Stage

Bake bites until cheese is melted and dough is golden brown, 18 to 20 minutes.

6 . Stage

Let cool 10 minutes in pan. Transfer bites to a platter. Top with thyme.
