French Onion Soup Bites Ingredients
For the Filling

• Beef Broth – Adds depth and a savory profile; easily swap this with vegetable broth for a vegetarian-friendly option.
• White Vinegar – Provides a touch of acidity to balance flavors; apple cider vinegar can offer a milder taste.

Step‑by‑Step Instructions for Savory French Onion Soup Bites
Step 1: Caramelize Onions
In a large skillet, heat 2 tablespoons of olive oil and 2 tablespoons of butter over medium heat. Add 4 thinly sliced yellow onions and cook for about 30 minutes, stirring frequently until they turn deep golden brown and are soft. The key here is patience; the more caramelized they are, the richer the flavor.
Step 2: Simmer Mixture
Stir in 1 cup of beef broth and 1 tablespoon of white vinegar to the caramelized onions. Allow the mixture to simmer for 5 minutes over low heat, letting the flavors meld together and the broth reduce slightly. Keep an eye on the consistency and ensure it’s not too watery for your French Onion Soup Bites.
Step 3: Prepare Dough
Preheat your oven to 375°F (190°C) and grease a mini muffin tin with cooking spray. While waiting for the oven to heat up, unroll 1 tube of crescent roll dough on a clean surface, and cut it into rectangles. Gently press each rectangle into the prepared mini muffin tin to create little cups.
Step 4: Fill Cups
Carefully spoon the caramelized onion mixture into each dough cup, filling them about three-quarters full. This will ensure room for the gooey topping. Then, generously sprinkle grated Gruyère cheese over the onion filling in each cup, allowing the cheese to melt beautifully during baking.
Step 5: Bake
Place the filled mini muffin tin in the oven and bake for 18-20 minutes. Keep an eye on them, and look for a golden-brown color and bubbly cheese on top. The alluring aroma of Savory French Onion Soup Bites will fill your kitchen!
Step 6: Serve
Once baked, remove the bites from the oven and allow them to cool for about 10 minutes. This will help them set and make them easier to remove from the tin. Gently remove each bite and garnish with fresh thyme leaves before serving to elevate the flavor and presentation.

Make Ahead Options
These Savory French Onion Soup Bites are perfect for meal prep enthusiasts looking to save time during busy weeknights! You can assemble the bites completely and refrigerate them for up to 24 hours before baking, which allows the flavors to meld beautifully without sacrificing quality. Alternatively, the caramelized onion mixture can be prepared in advance and stored in an airtight container in the refrigerator for up to 3 days. When ready to serve, simply fill the dough cups with the onion mixture, top with cheese, and bake as directed. This way, you’ll enjoy warm, restaurant-quality bites with minimal effort when guests arrive!
