Full Ingredients

For the Mushroom Mixture

• 12 oz (340 g) cremini or baby bella mushrooms, cleaned and sliced 1/4 inch thick
• 1 small shallot (about 30 g), finely chopped
• 2 garlic cloves, minced
• 1 tbsp unsalted butter
• 1 tbsp olive oil
• 2 tsp fresh thyme leaves (or 1 tsp dried)
• 1/2 tsp kosher salt
• 1/4 tsp freshly ground black pepper

For the Batter

• 2 cups (240 g) all-purpose flour
• 2 tsp baking powder
• 1/4 tsp baking soda
• 1/2 tsp kosher salt
• 1/4 tsp freshly ground black pepper
• 2 large eggs, at room temperature
• 3/4 cup (180 ml) whole milk, at room temperature
• 1/2 cup (120 g) plain full-fat Greek yogurt or sour cream, at room temperature
• 1/3 cup (80 ml) extra-virgin olive oil
• 1 tsp Dijon mustard
• 2 tbsp finely chopped fresh parsley (optional)
• 1 1/2 cups (150 g) coarsely shredded Gruyère, divided (reserve 2 tbsp for topping)

Step-by-Step Instructions

Step 1: Prep the pan and oven

Preheat the oven to 350°F (175°C) with a rack in the center. Grease a 9×5-inch loaf pan and line it with a parchment sling, leaving overhang on the long sides for easy lifting.

Step 2: Sauté the mushrooms until golden

Heat a large skillet over medium-high. Add the olive oil and butter. When the butter foams, add the mushrooms in an even layer. Cook undisturbed for 2 to 3 minutes to sear, then stir and continue cooking until the pan looks mostly dry and the mushrooms are deep golden, 7 to 9 minutes total. Season with the salt and pepper. Stir in the shallot and thyme and cook 2 minutes more until fragrant. Add the garlic and cook 30 seconds. Transfer to a plate to cool for 5 to 10 minutes so the heat does not melt the cheese in the batter.

Step 3: Mix the dry ingredients

In a large mixing bowl, whisk together the flour, baking powder, baking soda, kosher salt, and black pepper until well combined and aerated.

Step 4: Whisk the wet ingredients

In a separate bowl or large measuring jug, whisk the eggs, milk, yogurt (or sour cream), olive oil, and Dijon until smooth and fully emulsified. Stir in the parsley, if using.

Step 5: Make the batter and fold in the good stuff

Make a well in the dry ingredients and pour in the wet mixture. Using a spatula, gently fold just until a few flour streaks remain. Fold in the cooled mushroom mixture and all but 2 tablespoons of the Gruyère (reserve those for the top). The batter will be thick and scoopable; avoid overmixing for a tender crumb.

Step 6: Top and bake

Scrape the batter into the prepared pan and smooth the top. Sprinkle with the reserved 2 tablespoons Gruyère and a few extra thyme leaves, if you like. Bake for 50 to 60 minutes, until the loaf is deeply golden and a toothpick inserted in the center comes out clean or with a few moist crumbs (melted cheese streaks are fine). If the top is browning too quickly around 40 minutes, tent loosely with foil.

Step 7: Cool, slice, and serve

Cool in the pan for 15 minutes, then lift the loaf out using the parchment and cool at least 10 more minutes on a wire rack. Slice with a serrated knife and serve warm or at room temperature. It is excellent plain, with soft butter, or alongside soup or salad.

Pro Tips

• For best browning, pat mushrooms dry and avoid crowding the pan so they sear instead of steam.
• Room-temperature eggs and dairy help the batter come together quickly and prevent overmixing.
• Measure flour by weight (240 g) or use the spoon-and-level method for consistent texture.
• If your mushrooms release lots of liquid, cook until the skillet is nearly dry before cooling.
• Let the loaf rest at least 25 minutes total before slicing for cleaner cuts and a set crumb.

Variations

• Caramelized Onion & Comté: Swap Gruyère for Comté, fold in 1/2 cup deeply caramelized onions, and add a pinch of chopped rosemary.
• Spinach, Leek & Feta: Sauté 1 cup chopped leeks and 2 cups spinach until wilted and dry; fold in with 1 cup crumbled feta and lemon zest.
• Bacon, Cheddar & Chives: Fold in 4 slices cooked, crumbled bacon, 1 1/2 cups sharp cheddar, and 2 tbsp chopped chives; omit Dijon if preferred.

Storage & Make-Ahead

Cool completely, then wrap tightly. Store at room temperature for up to 2 days or refrigerate for up to 5 days. Freeze whole or sliced (separated by parchment) for up to 2 months; thaw overnight in the refrigerator. Reheat slices in a 325°F (165°C) oven or toaster oven for 8 to 10 minutes until warmed and edges are crisp. For make-ahead prep, sauté the mushroom mixture up to 3 days in advance; cool and refrigerate in an airtight container.
