Ingredients
For this creamy brunch spinach and potato gratin, gather these simple ingredients:

- 1 cup heavy cream
- 1 cup whole milk
- 1 cup shredded Gruyère cheese

Each ingredient plays an important role in this dish. The Yukon gold potatoes provide a buttery flavor and creamy texture when baked.

Make sure you have olive oil on hand to grease your baking dish. This helps prevent sticking and ensures easy serving later. Enjoy the process of gathering these ingredients for a delightful meal!

Step-by-Step Instructions
Preparation Steps
1. Preheat the oven and grease the baking dish: First, set your oven to 375°F (190°C). Use olive oil to grease a 9x13-inch baking dish. This helps prevent sticking.
2. Sauté onion and garlic: In a medium pan, melt 2 tablespoons of butter over medium heat. Add the finely chopped onion and sauté for 3-4 minutes. The onion should turn soft and clear. Next, stir in 2 cloves of minced garlic and cook for one more minute. Make sure the garlic doesn’t burn.
3. Assemble the cream mixture: In a large bowl, whisk together 1 cup of heavy cream, 1 cup of whole milk, 1 teaspoon of thyme, and a pinch of salt and pepper. Mix well to ensure all flavors blend nicely.
Layering the Gratin
1. First layer of potatoes, onions, and spinach: Start by layering half of the thinly sliced Yukon gold potatoes on the bottom of the prepared dish. Then, add half of the sautéed onions and half of the chopped spinach. Spread everything out evenly.
2. Adding cream and cheese: Pour half of the cream mixture over the first layer. Next, sprinkle one-third of the shredded Gruyère cheese over the top. Make sure to cover everything.
3. Repeat layering and topping with cheese: Now, repeat the layers. Add the rest of the potatoes, followed by the remaining onions and spinach. Pour the rest of the cream mixture over this layer. Finish by topping with the remaining Gruyère cheese and sprinkle the grated Parmesan on top.
Baking Instructions
1. Bake covered: Cover the dish tightly with aluminum foil. Place it in the preheated oven and bake for 30 minutes. This helps the flavors meld and the potatoes soften.
2. Bake uncovered for a golden top: After 30 minutes, remove the foil. Continue baking for another 20-25 minutes. Look for a golden brown top and bubbling sauce.
3. Rest before serving for best texture: Once it’s done, take the dish out of the oven. Let it rest for about 10 minutes. This helps the gratin set, making it easier to serve.
Tips & Tricks
Perfecting Your Gratin
- Importance of potato thickness
Slice the potatoes thinly, about 1/8 inch thick. This helps them cook evenly. Thicker slices may not soften well and can lead to a crunchy texture. Thin slices allow the cream to seep in, making each bite creamy and delicious.
- Substitutions for dairy
If you're avoiding dairy, use almond milk or oat milk instead of whole milk. For a creamy texture, consider coconut cream in place of heavy cream. Choose a dairy-free cheese for a similar taste if needed.
- Avoiding a watery gratin
To prevent a watery gratin, make sure to squeeze excess water from the spinach before adding it to the layers. This keeps the dish rich and creamy. Also, avoid overcooking the cream mixture; it should not be too runny before baking.
Presentation Suggestions
- Serving in ramekins
For a fun twist, serve the gratin in individual ramekins. This adds a personal touch and makes serving easier. Ramekins also help the gratin to cook evenly and create a lovely golden top.
- Garnishing options with fresh herbs
A sprinkle of fresh thyme or parsley on top adds color and flavor. Use finely chopped herbs to brighten the dish. Fresh herbs enhance the aroma and give a nice finish to your creamy brunch spinach and potato gratin.
Pro Tips
- Use a Mandoline for Perfect Slices: Utilizing a mandoline slicer ensures all potato slices are uniform in thickness, which helps them cook evenly and achieve that perfect creamy texture.
- Experiment with Cheese Varieties: While Gruyère adds a wonderful flavor, feel free to mix in other cheeses like Fontina or aged Cheddar for a unique twist on this gratin.
- Add Extra Flavor with Herbs: Consider incorporating additional herbs like rosemary or basil to enhance the dish's aroma and depth, elevating the overall taste experience.
- Let it Rest for Best Results: Allowing the gratin to rest after baking allows the layers to set, making it easier to serve and ensuring that each slice holds together beautifully.
Variations
Ingredient Alternatives
You can change the cheese for more flavor. Gruyère is tasty, but try cheddar or mozzarella. Both melt well and add character. You can also mix cheeses for a unique taste.
Want to add protein? Ham or bacon works great. Chop them into small pieces and layer them in. This adds a savory touch that pairs well with the creamy base. Vegans may use mushrooms or tofu for protein.
Seasoning Swaps
Fresh herbs can change the dish's flavor a lot. Instead of thyme, try basil or oregano. Both add a fresh taste. You can also mix in rosemary for a woodsy note.
Spices bring a kick. A pinch of nutmeg adds warmth and depth. For heat, sprinkle in red pepper flakes. These small changes can create a whole new gratin experience. Feel free to experiment!
Storage Info
Storing Leftovers
To keep your creamy brunch spinach and potato gratin fresh, store it in the fridge. Use a tight container to prevent air from getting in. This will keep the flavors strong. The gratin will stay good for about 3 to 5 days. If you want to save it longer, consider freezing it. Cut the gratin into portions and wrap them tightly in plastic wrap. Then, place them in a freezer bag. This way, you can enjoy a warm meal later.
Reheating Instructions
When you are ready to enjoy your leftovers, you can reheat them easily. The best way is to use the oven. Preheat the oven to 350°F (175°C). Place the gratin in an oven-safe dish. Cover it with foil to keep it moist. Heat it for about 20 minutes. If you want a crispy top, remove the foil for the last 5 minutes.
To restore the creaminess, add a splash of milk or cream before reheating. This will help bring back the rich texture. If you prefer the microwave, heat it in short bursts. Stir in between to make sure it heats evenly. This will keep your gratin delicious and creamy every time you enjoy it.
