How to Make French Onion Soup Mini Pies

Step 1: Preheat the Oven

Preheat your oven to 375° F. Line a baking sheet with parchment paper to ensure your mini pies bake perfectly.

Step 2: Caramelize the Onions

Melt together the butter and onions in a large skillet over medium-high heat.
Cook, stirring occasionally, until softened (about 5 minutes).
Gradually add the dry white grape juice, about 1/3 cup at a time, allowing it to cook into the onions.

Step 3: Add Remaining Ingredients

Stir in the garlic, mushrooms, thyme, and sage.
Continue cooking for another 10 minutes until the onions are deeply caramelized.
Add the broth and increase the heat to high; bring to a low boil.
Simmer for 5 minutes until the sauce has reduced; then stir in the cream.
Season with sea salt and pepper to taste.

Step 4: Prepare the Pastry

Lay the pastry sheets flat on a clean surface and gently roll them out slightly to stretch.
Cut each sheet into 3-inch circles.
Spoon some of the onion mixture onto each circle of pastry, topping with shredded Gruyère cheese while leaving a 1/4-inch border around the edges.
Brush the edges with beaten egg.

Step 5: Assemble Mini Pies

Fold the top half over the filling and crimp edges with a fork to seal tightly.
Place on prepared baking sheet; brush tops with beaten egg.
Make two small slits on top of each pie for ventilation.

Step 6: Bake

Freeze assembled pies for 15 minutes before baking them in preheated oven for 20-25 minutes or until golden brown.

Step 7: Serve Warm

Serve these delicious mini pies warm, topped with fresh thyme along with sea salt and pepper for extra flavor! Enjoy every bite of this delightful holiday treat!

How to Perfect French Onion Soup Mini Pies

To ensure your French Onion Soup Mini Pies are absolutely scrumptious, consider these handy tips:

Use High-Quality Cheese: Opt for good quality Gruyère cheese for a richer and creamier filling that melts beautifully.
Caramelize Onions Slowly: Take your time while caramelizing onions to develop deeper flavors. Patience pays off!
Thaw Puff Pastry Properly: Let puff pastry thaw in the refrigerator overnight for even baking and better texture.
Adjust Seasoning: Taste your filling before assembling and adjust seasoning as needed. A pinch more salt or pepper can enhance flavor dramatically.
Brush with Egg Wash: Brushing the tops with an egg wash before baking helps achieve that beautiful golden color.

Best Side Dishes for French Onion Soup Mini Pies

Common Mistakes to Avoid

Mistakes can happen when making French Onion Soup Mini Pies. Here are some common pitfalls and how to steer clear of them.

Using Too Much Butter: While butter adds flavor, too much can make the pies greasy. Stick to the recipe’s measurements for the best result.
Not Caramelizing Onions Properly: Under-cooked onions won’t have the depth of flavor needed. Be patient and allow them to caramelize slowly for optimal sweetness.
Skipping the Cheese: Gruyère cheese is essential for that rich flavor. Don’t omit it; instead, consider adding more if you love cheesy bites!
Ignoring Puff Pastry Thawing Instructions: If the pastry is not fully thawed, it won’t roll out properly. Always follow the package instructions for thawing.
Overfilling the Pies: It’s tempting to add more filling, but overfilling can lead to messy spills. Keep a 1/4-inch border around the edges to seal them effectively.
Not Preheating the Oven: Baking in an improperly heated oven can affect cooking times and texture. Always preheat your oven before baking.

Storage & Reheating Instructions
