Step‑by‑Step Instructions for French Onion Soup Bites
Step 1: Caramelize Onions
Heat 2 tablespoons of olive oil and 1 tablespoon of butter in a large skillet over medium heat. Add 4 sliced yellow onions, season with salt, and cook for about 30 minutes. Stir occasionally until the onions turn golden-brown and are beautifully caramelized, releasing their sweet aroma. This step is crucial for developing the flavors of your French Onion Soup Bites.
Step 2: Simmer Mixture
Once the onions have caramelized, stir in 1 cup of beef broth and 1 tablespoon of white vinegar. Bring the mixture to a gentle simmer over low heat for 5 minutes, allowing the broth to mostly absorb while enhancing the flavor. Keep an eye on the consistency; it should be thick and fragrant, perfect for filling your bites.
Step 3: Prepare Dough
Preheat your oven to 375°F (190°C). While it’s heating, unroll a tube of crescent roll dough and cut it into 3×3 inch squares. Lightly grease a mini muffin tin, then press each square into the tin, forming small cups that will hold the savory filling. Ensure the dough is snug against the sides to create sturdy bases for your French Onion Soup Bites.
Step 4: Fill Cups
Spoon the rich onion mixture into each prepared dough cup, filling them generously but not overflowing. Follow this by sprinkling grated Gruyère cheese on top of each filled cup for that gooey, melted goodness reminiscent of classic French onion soup. Make sure to cover the filling evenly for the best melt when baked.
Step 5: Bake
Place the muffin tin in the preheated oven and bake for 18-20 minutes or until the dough is golden-brown and the cheese is bubbling. Keep an eye on the bites; they should look appetizingly puffy and lightly browned. The delightful aroma wafting from your oven will signal that your French Onion Soup Bites are nearly ready.
Step 6: Cool and Serve
After baking, remove the bites from the oven and let them cool in the tin for about 10 minutes. This will help them set for easier removal. When ready to serve, garnish the top with fresh thyme leaves for an aromatic touch and inviting appearance. Serve warm to enjoy the full flavor of these cozy appetizers.
