Savory tarte tatin with caramelized mushrooms, melted Gruyère cheese, and golden puff pastry, served inverted on a ceramic plate with thyme garnish.

There’s something irresistibly satisfying about flipping a tarte tatin out of the pan. That moment when the pastry releases, revealing a glossy, golden surface beneath, feels almost theatrical. But when you replace apples with mushrooms and Gruyère, and swap sweetness for depth and umami, you get something even more compelling: a savory tarte tatin that balances elegance and earthiness in perfect symmetry.

This dish was born out of curiosity. Could the same inversion technique that gives fruit tarte tatins their caramelized finish be used to elevate something savory? The answer is yes—and spectacularly so. With the help of buttery puff pastry, wild mushrooms, and the nutty complexity of Gruyère, this version turns a classic on its head and lands squarely in fine dining territory. It’s not just beautiful—it’s bold, thoughtful, and layered.


Ingredients You Will Need

This dish depends on quality and restraint. Use the best cheese you can find, select mushrooms with character, and allow each layer to shine on its own.

🍄 For the Mushroom Base:

  • 2 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 2 cups mixed mushrooms, cleaned and sliced
  • 1 medium shallot, finely minced
  • 1 teaspoon fresh thyme leaves
  • ½ teaspoon sea salt
  • ¼ teaspoon black pepper

🧀 For the Gruyère Layer:

  • ¾ cup Gruyère cheese, grated
  • 1 tablespoon heavy cream
  • 1 egg yolk

🥧 For the Tarte Tatin Assembly:

  • 1 sheet puff pastry, thawed
  • 1 tablespoon Dijon mustard
  • 1 egg, beaten (for egg wash)
  • Savory tart shells (if making individual portions)

💡 Pro Tip: Use a well-seasoned cast iron or oven-safe skillet to get a beautiful, even caramelization on the mushroom layer.


Step 1: Preparing the Mushroom Filling

Ingredients Used:

✔ Butter, olive oil, mushrooms, shallot, thyme, salt, pepper

Method:

1️⃣ Sauté the Mushrooms:

Heat butter and olive oil in a skillet over medium heat. Add mushrooms in a single layer and let them brown without stirring for 3–4 minutes. Flip and cook an additional 2–3 minutes.

2️⃣ Add Aromatics:

Stir in shallot and thyme, reduce heat slightly, and cook for another 3 minutes until everything is golden and fragrant. Season with salt and pepper.

3️⃣ Cool Slightly:

Remove from heat and allow to cool slightly while you prepare the other components.

💡 Chef’s Note: Avoid crowding the pan—browning gives mushrooms their texture and umami depth.


Step 2: Creating the Cheese Base and Layering

Ingredients Used:

✔ Gruyère, cream, egg yolk

Method:

1️⃣ Make the Cheese Blend:

In a small bowl, combine Gruyère, heavy cream, and egg yolk. Stir into a smooth, spreadable mixture.

2️⃣ Line the Skillet:

Spread the mushroom mixture evenly across the base of the same skillet you sautéed in.

3️⃣ Add the Cheese Layer:

Spoon the Gruyère mixture on top of the mushrooms and gently spread it into an even layer.

💡 Pro Tip: This layer will bake into the mushrooms, creating a rich, bubbling base under the pastry.


Step 3: Assembling and Baking the Tarte Tatin

Ingredients Used:

✔ Puff pastry, Dijon mustard, egg

Method:

1️⃣ Apply the Mustard:

Spread a thin layer of Dijon mustard over the center of your puff pastry sheet. This adds acidity and balance to the richness.

2️⃣ Cover the Skillet:

Lay the puff pastry over the mushroom and cheese layers, mustard-side down. Tuck the edges in slightly to form a seal.

3️⃣ Brush and Bake:

Brush the surface with egg wash and cut a small steam vent in the center. Bake in a 400°F (200°C) oven for 25–30 minutes until puffed and deeply golden.

4️⃣ Flip and Serve:

Let cool for 5 minutes, then carefully invert the tart onto a serving plate to reveal the mushroom-glazed surface.

💡 Presentation Tip: Garnish with fresh thyme or microgreens. Serve on a wide, flat plate for a minimalist, refined finish.


Perfect Pairings Suggestions

🧀 Cheese: A wedge of aged Comté adds a crystalline texture that echoes the Gruyère’s nutty depth without overpowering it.

🍶 Infused Oil: A drizzle of black truffle oil before serving adds aroma and elegance that complements the mushrooms beautifully.

🥣 Side: Serve with a small bowl of warm parsnip purée or celery root mash for an earthy, comforting contrast to the tart’s crisp shell.

🍷 Digestif: A splash of dry vermouth or chilled white port enhances the savory finish and balances the pastry’s richness.


Frequently Asked Questions (FAQs)

1. Can I make this in individual portions?

✔ Yes, simply use savory tart shells and reduce baking time by 5–7 minutes.

2. What’s the best way to flip the tarte tatin cleanly?

✔ Use a wide plate and oven mitts. Place the plate over the skillet, hold firmly, and invert in one smooth motion.

3. Can I make this ahead of time?

✔ The tart can be baked and reheated gently in the oven. However, for best texture, flip and serve immediately after baking.

4. Is puff pastry essential for this recipe?

✔ Yes. Puff pastry provides the light, flaky contrast to the dense mushroom and cheese base—crucial for a proper tarte tatin texture.
