How to Make French Onion Cups
Follow these simple steps to prepare this delicious dish:
Step 1: Prepare the Onions
Start by slicing your onions thinly. In a large skillet, melt butter over medium heat and add your sliced onions. Sauté them slowly until they become golden brown and caramelized—this will take about 20-25 minutes but trust me, it’s worth it!
Step 2: Add Flavor
Once your onions are gloriously caramelized, sprinkle in some fresh thyme and pour in the beef broth. Let this mixture simmer for about five minutes until it slightly thickens.
Step 3: Preheat Oven
While your onion mixture simmers away like a warm hug on a chilly day, preheat your oven to 400°F (200°C). Line a muffin tin with parchment paper or grease it lightly.
Step 4: Assemble Your Cups
Roll out your puff pastry sheets on a floured surface and cut them into squares big enough to fit snugly into each muffin cup. Gently press each square into the muffin tin.
Step 5: Fill ‘Em Up
Spoon generous amounts of the onion mixture into each pastry cup until they are filled almost to the top. Don’t be shy!
Step 6: Cheese Please!
Top each filled pastry cup with shredded cheese—Gruyère works wonders here! Pop them in the oven and bake for about 15-20 minutes until the pastry is golden brown and crispy.
Transfer to plates and serve hot! Drizzle any remaining beef broth reduction over them if you like extra sauciness.
Now you’re all set to wow your friends and family with these charming French Onion Cups! Each bite offers a taste of warmth and comfort—perfect for chilly evenings or festive gatherings where laughter fills the air!

FAQs:
What are French Onion Cups made of?
French Onion Cups are delicious appetizers featuring a rich blend of caramelized onions, savory cheese, and crispy pastry. Typically, you start with thinly sliced onions, slowly cooked to bring out their natural sweetness. These are combined with beef or vegetable broth, herbs, and topped with melted cheese, often Gruyère or mozzarella. The filling is then placed in mini pastry cups or phyllo dough shells that add a delightful crunch. This combination creates a perfect bite-sized treat that’s ideal for parties or casual gatherings.
How do I store leftover French Onion Cups?
If you have any French Onion Cups left over after your gathering, storing them properly ensures they maintain their flavor and texture. Allow the cups to cool completely before transferring them to an airtight container. Place parchment paper between layers to avoid sticking. Store them in the refrigerator for up to three days. To reheat, place them in the oven at 350°F (175°C) for about 10-15 minutes until warmed through. Avoid microwaving as it can make the pastry soggy.
Can I make French Onion Cups ahead of time?
Absolutely! Preparing French Onion Cups ahead of time can save you stress on party day. You can prepare the onion filling and pastry cups separately. Store the filling in the fridge for up to two days and keep the pastry cups at room temperature. When ready to serve, fill the cups with the onion mixture and top with cheese just before baking. This method allows you to enjoy freshly baked French Onion Cups without all the last-minute work.
What drinks pair well with French Onion Cups?
French Onion Cups pair wonderfully with a variety of beverages that complement their rich flavors. For wine lovers, a crisp Sauvignon Blanc or a light red like Pinot Noir enhances the dish beautifully. If you prefer cocktails, consider serving a refreshing gin and tonic or a classic mojito for contrast. Non-alcoholic options like sparkling water with lemon or iced tea also work well, balancing the savory notes of these delightful appetizers.
