How to Make French Onion Soup Bites

Cook Onions: In a skillet, sauté sliced onions in extra-virgin olive oil and unsalted butter over medium heat, adding kosher salt and freshly ground black pepper. Stir until the onions are caramelized, about 25 minutes, reaching a lovely golden brown color.
Add Broth and Vinegar: Once the onions are beautifully caramelized, stir in the low-sodium beef broth and sherry vinegar. Let it simmer for an additional 5 minutes until slightly thickened, creating a luscious filling.
Prepare Crescent Rolls: On a floured surface, roll out the crescent dough from the cans. Cut the dough into squares, ensuring they are big enough to hold your filling.
Fill Dough: Place a spoonful of the savory onion mixture and a generous sprinkle of grated Gruyère cheese on each dough square. Fold the dough over and seal the edges tightly to keep the delicious filling inside.
Bake: Arrange the filled bites on a baking sheet and spray the tops with cooking spray. Bake in a preheated oven at 375°F (190°C) for about 15-18 minutes or until the bites are golden brown and flaky.
Serve: Once baked, garnish your French Onion Soup Bites with fresh thyme and serve while warm for the best experience!

Optional: For an extra savory touch, add crispy bacon bits to the filling.

Tips for the Best French Onion Soup Bites

French Onion Soup Bites Recipe FAQs

What type of onions are best for French Onion Soup Bites?
Absolutely, large yellow onions are ideal for this recipe! Their natural sweetness caramelizes beautifully, enhancing the overall flavor of your bites. If you prefer a sharper taste, you could also mix in a small amount of red onions for added depth.

How long can I store leftover French Onion Soup Bites?

Can I freeze French Onion Soup Bites? How do I do it?
Yes, you can! To freeze them, prepare the bites but don’t bake them. Instead, place the filled, unbaked bites on a baking sheet lined with parchment paper and freeze until firm. Once frozen, transfer them to a freezer bag or container. They can be kept for up to 3 months! When you’re ready to bake, just add a few extra minutes to the baking time since they’ll be starting from frozen.

What should I do if my crescent dough doesn’t roll out correctly?
Very common! If your crescent dough feels too sticky or hard to manage, let it sit at room temperature for about 5-10 minutes. This often makes it easier to handle. Additionally, ensure your floured surface is truly floured to avoid sticking.

Are French Onion Soup Bites suitable for people with gluten allergies?
Unfortunately, traditional crescent rolls contain gluten, so they aren’t suitable for those with gluten allergies. However, you can use gluten-free crescent dough substitutes available at most grocery stores. Just be sure to check the packaging to ensure it’s appropriate for your needs.

The more the merrier! To elevate the flavor, consider adding a pinch of crushed garlic or fresh herbs like thyme or rosemary when sautéing the onions. For an extra savory kick, you could even mix in cooked bacon bits to give those bites a delightful twist.
