- Heavy cream – Optional but recommended for a luxuriously smooth custard in your Mushroom and Gruyère Strata.
For the Mushroom Mixture

For the Cheese

Seasonings & Finishing Touches
- Salt and freshly ground black pepper – Essential for seasoning every layer perfectly.

How to Make Mushroom and Gruyère Strata
- Preheat: Preheat oven to 350°F. Grease a 9×13 baking dish with butter, ensuring every corner is coated to prevent sticking and add richness.
For the Mushroom Mixture:
- Sauté: Cook mushrooms, shallots, garlic, and thyme in butter until golden brown and tender, about 6–8 minutes, stirring until moisture evaporates and edges crisp.
For the Custard:
-
Whisk: Combine eggs, whole milk, heavy cream, salt, and pepper in a bowl, whisking until smooth, pale, and slightly frothy for a creamy texture.
-
Soak: Arrange bread cubes in the prepared dish. Pour custard evenly over bread, gently pressing to coat; let rest 30 minutes at room temperature or refrigerate overnight.
-
Layer: Scatter sautéed mushrooms over soaked bread, then top with grated Gruyère and optional Parmesan, ensuring even coverage for gooey, cheesy pockets in every bite.
-
Bake: Bake at 350°F for 40–45 minutes until the top is golden brown and the center is set but still slightly custardy.
-
Rest: Allow the strata to cool for 10 minutes before slicing; this helps the layers set and makes serving neat and warm.
Optional: Sprinkle chopped parsley for a fresh pop of color and flavor.

Tips for the Best Mushroom and Gruyère Strata
- Use Day-Old Bread: Stale bread soaks up the custard perfectly without turning mushy, ensuring your strata holds its shape with a tender bite.
- Sauté Mushrooms Thoroughly: Cook mushrooms until all moisture evaporates to prevent a soggy strata and to deepen their rich, earthy flavor.
- Whisk Custard Well: Beat eggs, milk, and cream until frothy to create a light, fluffy custard that evenly soaks the bread for perfect texture.
- Rest Before Baking: Letting the strata sit for at least 30 minutes (or overnight) allows the bread to absorb custard fully, resulting in a cohesive, flavorful dish.
- Don’t Overbake: Remove the strata when the center is just set but still slightly custardy to keep it moist and creamy, avoiding dryness.
- Fresh Herbs Finish: Sprinkle fresh parsley right before serving to add a burst of brightness that complements the Mushroom and Gruyère Strata beautifully.

Mushroom and Gruyère Strata Recipe FAQs
What type of bread works best for Mushroom and Gruyère Strata?
Day-old, sturdy breads like French bread or sourdough are ideal because they soak up the custard without falling apart. Fresh bread can get too soggy, while stale bread provides just the right texture.
How long can I store leftover strata in the fridge?
You can keep leftovers in an airtight container for up to 3 to 4 days. When reheating, warm individual portions in the microwave or oven until heated through to enjoy that rich, gooey texture again.
Can I freeze Mushroom and Gruyère Strata?
Absolutely! Freeze the unbaked strata wrapped tightly in plastic wrap and aluminum foil for up to 2 months. When ready, thaw it overnight in the fridge, then bake at 350°F for 30–35 minutes until warmed through and the top crisps up nicely.
Why did my strata turn out soggy, and how can I prevent that?
Sogginess often happens if the mushrooms aren’t sautéed long enough or the bread is too fresh. Be sure to cook the mushrooms until all moisture evaporates and use bread that’s a day or two old. Also, allow the strata to rest for at least 30 minutes before baking so the custard absorbs evenly.
Is this recipe safe for pets or people with dairy allergies?
This strata contains dairy-rich Gruyère and heavy cream, so it’s not suitable for those with lactose intolerance or dairy allergies, and definitely avoid feeding it to pets. For alternatives, consider vegan cheese substitutes and plant-based milk to adapt the recipe.
