Ingredients You’ll Need
Every ingredient here plays an essential role in bringing this Mini Roasted Beef and Gruyère Savory Tarts Recipe to life. From the flaky puff pastry that holds everything together to the rich Gruyère cheese that melts beautifully, these simple components create harmony in every bite.
- 1 sheet puff pastry (thawed): Provides the crisp, flaky base that makes these tarts so irresistibly delicate and buttery.
- 1 tablespoon olive oil: Used for gently caramelizing the onions, adding depth and subtle richness.
- 1 small yellow onion (thinly sliced): When caramelized, adds a sweet, savory layer of flavor that complements the beef perfectly.
- 1/2 teaspoon salt: Enhances the natural flavors and balances the sweetness of the onions.
- 1/4 teaspoon black pepper: Adds a mild kick of warmth and complexity.
- 1 teaspoon fresh thyme leaves (or 1/4 teaspoon dried): Infuses a gently earthy, herbaceous note that ties the filling together.
- 3/4 cup cooked roasted beef (thinly sliced or shredded): The star protein, tender and flavorful, adding hearty richness to the tarts.
- 3/4 cup shredded Gruyère cheese: Melts into a creamy, nutty custard that’s absolutely luscious.
- 2 large eggs: Combine with cream to create a silky filling that holds the tart together.
- 1/2 cup heavy cream: Adds richness and helps create that smooth custard texture.
- 1 teaspoon Dijon mustard: Lends a subtle tangy note that brightens the overall flavor.
- Fresh parsley for garnish (optional): Adds a fresh, vibrant touch and a pop of color on top.
How to Make Mini Roasted Beef and Gruyère Savory Tarts Recipe
Step 1: Prepare the Tart Shells
First, preheat your oven to 375°F and lightly grease a muffin tin or mini tart pans to ensure the tarts pop out easily after baking. Roll out the thawed puff pastry and cut it into circles that fit snugly into your tins. Gently press the circles into the bottoms and up the sides, creating a perfect little vessel ready to hold all that delicious filling.
Step 2: Caramelize the Onions
In a skillet over medium heat, warm the olive oil. Add the thinly sliced onions along with salt, pepper, and thyme, and cook slowly. This step takes about 10 to 12 minutes, during which the onions develop a beautiful golden hue and a sweet, mellow flavor that forms the aromatic backbone of the tart’s filling.
Step 3: Mix the Custard Filling
While the onions soften, whisk together the eggs, heavy cream, and Dijon mustard in a bowl until the mixture is smooth and cohesive. This custard will bake up silky and creamy, soaking up the flavors from the beef and cheese without overpowering their delicate balance.
Step 4: Assemble the Tarts
Fill each puff pastry shell with a small spoonful of the caramelized onions, followed by an ample amount of roasted beef and a sprinkle of shredded Gruyère cheese. Pour the egg and cream mixture gently over the fillings, keeping the custard just below the edge of the pastry to avoid spills in the oven.
Step 5: Bake to Perfection
Bake the tarts for around 20 to 25 minutes until the custard is fully set and the tops have turned a gorgeous golden brown. Once out of the oven, let them cool slightly in the tin before removing to avoid any breaks in the delicate shells.
How to Serve Mini Roasted Beef and Gruyère Savory Tarts Recipe
Garnishes
A sprinkle of fresh parsley just before serving brings a burst of color and freshness that cuts through the richness. For an extra flourish, a few thyme sprigs or a light dusting of cracked black pepper also work wonders.
Side Dishes
These tarts pair beautifully with light, refreshing sides like a crisp mixed greens salad tossed in a simple vinaigrette or roasted seasonal vegetables. Their richness also invites creamy mustard or horseradish sauces for dipping, adding an exciting twist.
Creative Ways to Present
For parties or gatherings, present these mini tarts on a rustic wooden board or a sleek slate platter, garnished with small bowls of mustard or chutney on the side. You can also serve them alongside a charcuterie board featuring cured meats and pickles to elevate the experience into a full flavor journey.
Make Ahead and Storage
Storing Leftovers
Leftover mini tarts keep well when stored in an airtight container in the refrigerator for up to three days. Gently cover them to avoid drying out the delicate pastry and custard while preserving their incredible flavors.
Freezing
Once fully cooled, you can freeze these tarts in a single layer on a baking sheet until firm, then transfer them to a freezer-safe container or bag. They’ll maintain their deliciousness for up to two months, making them a perfect make-ahead option for unexpected guests or busy days.
Reheating
To enjoy leftovers or frozen tarts, reheat in a preheated oven at 350°F for 5 to 10 minutes until warmed through and crispy again. This method keeps the puff pastry flaky and the filling perfectly creamy without making it soggy or rubbery.
FAQs
Can I use a different cheese instead of Gruyère?
Absolutely! While Gruyère offers a beautiful nutty flavor and melts wonderfully, you can substitute Swiss cheese or a sharp white cheddar for a slightly different but equally tasty profile.
Is it possible to make these tarts gluten-free?
They’re traditionally made with puff pastry, which contains gluten, but you can find gluten-free puff pastry alternatives in some stores or make your own if you’re up for it. The filling remains naturally gluten-free, so swapping the base is the key.
How far in advance can I assemble these tarts before baking?
You can assemble the tarts and store them covered in the refrigerator for up to 4 hours in advance. This makes your prep smooth, especially when entertaining, just bake them fresh when guests arrive.
Can I swap the roasted beef for another protein?
For sure! Roast chicken or turkey work nicely as milder options, and for a vegetarian twist, try sautéed mushrooms or caramelized eggplant with extra herbs to keep that rich flavor.
What’s the best way to get perfectly caramelized onions?
Patience and low heat are your best friends here. Slowly cook thinly sliced onions in olive oil, stirring occasionally, for at least 10 minutes until they soften and turn golden brown without burning. This slow approach maximizes sweetness and flavor.
Final Thoughts
I can’t recommend enough giving the Mini Roasted Beef and Gruyère Savory Tarts Recipe a try.

Ingredients
Puff Pastry and Filling
- 1 sheet puff pastry (thawed)
- 1 tablespoon olive oil
- 1 small yellow onion (thinly sliced)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 teaspoon fresh thyme leaves (or 1/4 teaspoon dried)
- 3/4 cup cooked roasted beef (thinly sliced or shredded)
- 3/4 cup shredded Gruyère cheese
Custard Mixture
- 2 large eggs
- 1/2 cup heavy cream
- 1 teaspoon Dijon mustard
Garnish
- Fresh parsley for garnish (optional)
Instructions
- Preheat and Prepare Tart Shells: Preheat your oven to 375°F (190°C). Lightly grease a muffin tin or mini tart pans to prevent sticking. Roll out the thawed puff pastry and cut into circles large enough to line the tart tins. Press the pastry gently into the bottoms and up the sides to form the tart shells.
- Caramelize Onions: Heat olive oil in a skillet over medium heat. Add the thinly sliced onions along with salt, black pepper, and thyme. Cook slowly, stirring occasionally, until the onions become golden and caramelized, about 10–12 minutes. This step builds deep flavor for the filling.
- Mix Custard: In a mixing bowl, whisk together the eggs, heavy cream, and Dijon mustard until the mixture is smooth and well combined. This custard will bind the filling ingredients together in the tart.
- Assemble Tarts: Place a small spoonful of caramelized onions into each tart shell, followed by some roasted beef and a sprinkle of shredded Gruyère cheese. Carefully pour the egg custard over the filling in each tart, taking care not to overfill and spill over the edges.
- Bake: Place the filled tart pans into the preheated oven and bake for 20–25 minutes. Bake until the custard is set in the center and the pastry edges turn golden brown and flaky.
- Cool and Serve: Remove the tarts from the oven and allow them to cool slightly in the tin before gently removing. Garnish with fresh parsley if desired and serve warm or at room temperature for best flavor and texture.
Notes
- Gruyère cheese can be substituted with Swiss or sharp white cheddar for different flavors.
- These tarts can be made ahead of time and reheated in the oven at 350°F for 5–10 minutes.
- Baked tarts freeze well once cooled; reheat before serving for a quick appetizer.
