Ingredients You’ll Need
This recipe calls for simple, accessible ingredients that each play a key role in creating a perfect balance of taste, texture, and color. From the creamy eggs to the crispy bacon and golden puff pastry, every component shines in harmony.
- 5 eggs: The star of the filling that brings richness and structure.
- 1 tbsp Dijon mustard: Adds a subtle tanginess that brightens the flavor.
- 2 tbsp thick sour cream or creme fraiche: Provides creaminess and smoothness to the custard; mayonnaise works well as a substitute.
- 2/3 cup grated Gruyere cheese (divided): Brings a nutty, melty goodness that elevates the tart.
- Salt and pepper: Essential seasonings to enhance every bite.
- 1 sheet store bought frozen puff pastry (thawed, 25 cm x 25cm / 10″ x 10″): The buttery, flaky base that makes this tart irresistible.
- 1 tbsp butter (salted or unsalted): For sautéing mushrooms to perfection.
- 5 oz / 150g mushrooms (sliced, about 2 cups): Adds an earthy depth and a tender bite.
- 6 – 8 oz / 200 – 250g bacon (roughly chopped): Infuses smoky, crispy flavor that pairs wonderfully with all other ingredients.
How to Make Bacon, Egg and Mushroom Tart (Puff Pastry) Recipe
Step 1: Prepare Your Oven and Baking Tray
Start by preheating your oven to 180°C (350°F). While it warms up, lightly spray or grease a baking tray. This sets the stage for baking the puff pastry evenly and crispily without sticking.
Step 2: Cook the Bacon and Mushrooms
In a skillet over medium heat, add the chopped bacon and cook until it’s crispy and golden. Remove the bacon and set it on a paper towel to drain excess fat. In the same pan, melt the butter and sauté the sliced mushrooms until they’re tender and slightly caramelized. The mix of bacon and mushrooms builds a flavorful, savory layer that forms the heart of this tart.
Step 3: Prepare the Egg Mixture
In a bowl, whisk together the eggs, Dijon mustard, sour cream (or creme fraiche), half of the grated Gruyere cheese, salt, and pepper. This creamy custard is key to giving the tart its lovely, soft texture and rich taste.
Step 4: Assemble the Tart
Roll out the thawed puff pastry onto your baking tray, gently pressing it into shape and making sure the edges are slightly raised to hold the filling. Evenly sprinkle the cooked bacon and mushrooms over the pastry base. Pour the egg mixture on top, then finish by sprinkling the remaining Gruyere cheese over the whole tart. This layering ensures every bite has a bit of everything.
Step 5: Bake to Perfection
Place the assembled tart in the preheated oven and bake for about 20 minutes or until the pastry is golden brown and puffed up, and the egg custard is set but still tender. Let it cool slightly before slicing; it helps the tart hold together better and makes serving easier.
How to Serve Bacon, Egg and Mushroom Tart (Puff Pastry) Recipe
Garnishes
To add a fresh pop of color and flavor, scatter chopped fresh parsley or chives over the tart just before serving. A light drizzle of extra virgin olive oil or a sprinkle of flaky sea salt can elevate the flavors beautifully as well.
Side Dishes
This savory tart pairs wonderfully with a crisp green salad dressed in lemon vinaigrette or a simple tomato and cucumber salad. For a heartier meal, consider serving alongside roasted new potatoes or a bowl of fresh fruit to balance the richness.
Creative Ways to Present
If you want to impress guests, cut the tart into small squares or rectangles for a stylish platter of bite-sized treats. It also tastes fantastic as a warm, handheld slice perfect for brunch gatherings or picnic boxes.
Make Ahead and Storage
Storing Leftovers
Once cooled, wrap any leftover tart tightly in plastic wrap or store in an airtight container. It keeps well in the refrigerator for up to 3 days while maintaining its flavors and texture.
Freezing
You can freeze the leftover tart by wrapping it securely in foil and then placing it in a freezer bag. Freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
To bring back its crispiness, reheat the tart in a preheated oven at 180°C (350°F) for about 10 minutes until warmed through and the pastry regains its flakiness. Avoid the microwave, which could make the pastry soggy.
FAQs
Can I use a different type of cheese in this recipe?
Absolutely! While Gruyere adds a lovely nutty flavor and melts beautifully, you can substitute it with cheddar, mozzarella, or even a Swiss cheese depending on your preference and what you have on hand.
Is it possible to make this tart vegetarian?
Yes! Simply omit the bacon and increase the quantity of mushrooms or add other vegetables like spinach or roasted bell peppers for extra flavor and texture.
Do I need to use store-bought puff pastry, or can I make my own?
Store-bought puff pastry is a time-saving convenience that works perfectly here, but if you enjoy making pastry from scratch, homemade puff pastry will definitely add a personal touch and superb flakiness.
Can I prepare this tart in advance before baking?
You can assemble the tart and keep it covered in the fridge for a few hours before baking. Just remember to bake it straight from the fridge, adding a couple of extra minutes to the baking time if needed.
What’s the best way to slice the tart for serving?
Use a sharp knife to cut the tart into squares or triangles, wiping the blade between cuts if needed to keep edges clean and neat.

Ingredients
Egg Mixture
- 5 eggs
- 1 tbsp Dijon mustard
- 2 tbsp thick sour cream or creme fraiche (or substitute with mayonnaise)
- 2/3 cup grated gruyere cheese, divided (2 x 1/3 cup, or any other melting cheese)
- Salt and pepper, to taste
Pastry and Toppings
- 1 sheet store-bought frozen puff pastry, thawed (25 cm x 25 cm / 10″ x 10″)
- 1 tbsp butter (salted or unsalted)
- 5 oz / 150 g mushrooms, sliced (approximately 2 cups sliced)
- 6 – 8 oz / 200 – 250 g bacon, roughly chopped
Instructions
- Preheat and Prepare Baking Tray: Preheat your oven to 180°C (350°F). Lightly spray a baking tray with oil to prevent sticking.
- Sauté Mushrooms: In a skillet over medium heat, melt the butter. Add the sliced mushrooms and sauté until they release their moisture and become golden brown, about 5-7 minutes. Remove from heat and set aside.
- Cook Bacon: In the same pan or a separate skillet, cook the roughly chopped bacon over medium heat until crispy. Drain on paper towels to remove excess fat.
- Prepare Egg Mixture: In a mixing bowl, whisk together the eggs, Dijon mustard, sour cream (or creme fraiche/mayonnaise), half of the grated gruyere cheese, and salt and pepper to taste. Mix until smooth and well combined.
- Assemble Tart: Place the thawed puff pastry sheet on the prepared baking tray. Spread the sautéed mushrooms evenly over the pastry, then sprinkle the crispy bacon pieces on top. Pour the egg mixture evenly over the mushroom and bacon layer, then sprinkle with the remaining gruyere cheese.
- Bake the Tart: Place the tart in the preheated oven and bake for 18-20 minutes, or until the pastry is golden brown and the egg filling is set and slightly puffed.
- Serve: Allow the tart to cool slightly before slicing into 4 portions. Serve warm for the best flavor and texture.
Notes
- Make sure to thaw the puff pastry completely before assembling the tart to ensure even cooking.
- You can substitute gruyere cheese with cheddar, mozzarella, or any good melting cheese you prefer.
- For a vegetarian version, omit the bacon and add more mushrooms or your favorite vegetables.
- Use salted or unsalted butter according to your taste preference; adjust the added salt accordingly since bacon and cheese add saltiness.
- This tart is delicious served with a simple green salad on the side for a complete meal.
