-
Preheat your oven to 375°F (190°C) and butter a medium baking dish. This will ensure a beautifully baked gratin that won’t stick!
-
Melt the butter in a skillet over medium heat until bubbling. Add the minced garlic and shallots, sautéing for 1-2 minutes until fragrant and light golden.

Add the sliced mushrooms to the skillet. Cook for 6-8 minutes, stirring occasionally, until the mushrooms release their juices and most evaporate—this enhances the flavor!
-
Season the mushrooms with salt, black pepper, and thyme, stirring until fully coated in the herbs and seasoning. Give it a moment to blend those delicious flavors!

Pour in the heavy cream, allowing it to come to a gentle simmer. This thickening step is crucial for that creamy texture; watch for bubbles!

Make Ahead Options
These Mushroom Gratin are perfect for busy home cooks looking to save time during the week! You can prepare the entire dish up to 24 hours in advance by assembling the gratin and refrigerating it in the baking dish, which allows the flavors to meld beautifully. Simply cover it tightly with plastic wrap to prevent drying out. When you’re ready to serve, remove the plastic, and bake it directly from the refrigerator for about 30-35 minutes, or until it’s golden and bubbling. This way, you’ll enjoy restaurant-quality results with minimal effort, ensuring your cozy comfort food night is both effortless and satisfying!
Expert Tips for Mushroom Gratin

Flavor Boost: Incorporate sautéed shallots or nutmeg for an extra layer of complexity in your Mushroom Gratin. These additions can elevate the dish unexpectedly!
