Rice Gratin Recipe: Cheesy Baked Comfort With Golden Crust

This baked rice gratin delivers comfort in every bite, with layers of creamy, cheesy rice topped by a golden crust that crackles with each spoonful. The dish transforms simple ingredients into something extraordinary through careful baking.

The secret lies in the technique: par-cooking the rice in a rich cream sauce before baking ensures every grain absorbs maximum flavor. A final broil creates that signature crisp top without drying the dish.

What emerges from the oven is a casserole that’s creamy beneath its crisp surface, with melted cheese pulling in long, delicious strands. The aroma alone promises warmth and satisfaction.

Perfect for family dinners or cozy gatherings, this recipe turns humble rice into a dish worthy of celebration.

Ingredients for Rice Gratin

Transform humble rice into luxurious comfort with these carefully selected ingredients.

The cheese selection is paramount. Gruyère provides the ideal melt and nutty depth, while Parmesan adds the sharp finish. Source both from a reputable cheese counter—Whole Foods or a local specialty shop—where they cut wedges to order. The heavy cream should be organic if possible for superior richness. Avoid pre-shredded cheese, as it contains anti-caking agents that inhibit melting.

For the Gruyère, Emmental works as a substitute with similar melt characteristics. No shallots? Yellow onion at half the volume provides comparable sweetness. Out of Dijon? Whole-grain mustard at equal quantity adds a different but pleasant texture. The rice must be long-grain—jasmine or basmati work well if white rice isn’t available.

Assemble the gratin just before baking for optimal texture. Refrigerate leftovers in an airtight container for up to 3 days. Reheat in the oven at 350°F until warmed through and crisp. Not suitable for freezing due to the cream base separating upon thawing.

Step-by-Step Instructions for Cheesy Rice Gratin

Master this technique for a velvety rice base with a perfectly crisp golden topping.

Step 1: Cook the Rice and Prepare Aromatics

Rinse the 1.5 cups Long-Grain White Rice thoroughly under cold water until the water runs clear. This removes excess starch and prevents a gummy texture. Cook the rice according to package instructions, but undercook it by 2 minutes—it will finish in the oven.

While the rice cooks, finely dice the 1 whole Shallot and mince the 3 cloves Garlic Cloves. Sauté them in 2 tbsp Unsalted Butter over medium heat for 3-4 minutes until the shallot becomes translucent and the garlic is fragrant but not browned. This builds the aromatic foundation for your gratin.

Step 2: Create the Creamy Cheese Sauce

In the same pan, melt the remaining 2 tbsp Unsalted Butter over medium heat. Whisk in the 2 tbsp All-Purpose Flour to form a roux, cooking for 1-2 minutes until it turns a light golden color. This step thickens the sauce and removes the raw flour taste.

Gradually whisk in the 2 cups Heavy Cream and 1 cup Whole Milk until smooth. Stir in the 1 tbsp Dijon Mustard, 0.25 tsp Nutmeg, 1.5 tsp Salt, and 0.5 tsp Black Pepper. Simmer for 3-4 minutes until the sauce thickens enough to coat the back of a spoon.

Step 3: Combine Rice and Sauce with Cheese

In a large bowl, combine the cooked rice, the cream sauce, and the 1.5 cups Gruyère Cheese. Stir gently but thoroughly to ensure every grain is coated. The Gruyère should be shredded from a block to ensure smooth melting without the anti-caking agents found in pre-shredded cheese.

Taste and adjust seasoning if needed. The mixture should be creamy but not soupy—it will thicken further during baking. Transfer everything to a greased 9×13-inch baking dish or similar oven-safe dish, spreading it into an even layer.

Step 4: Add Topping and Bake to Perfection

In a small bowl, mix the 0.5 cup Panko Breadcrumbs with the 0.5 cup Parmesan Cheese. Sprinkle this mixture evenly over the rice, pressing down lightly to help it adhere. This creates the crisp, golden crust that contrasts beautifully with the creamy interior.

Bake at 375°F for 25-30 minutes until the top is golden brown and the edges are bubbling. For an extra-crispy finish, broil for 1-2 minutes at the end, watching closely to prevent burning. Let it rest for 5 minutes before serving to allow the gratin to set.

Essential Equipment for Perfect Results

Oven-Safe Dish

For this recipe, a 9×13-inch baking dish is ideal, but any oven-safe dish with similar capacity works. I prefer stoneware from Le Creuset—it distributes heat evenly and looks beautiful on the table. A 2-quart casserole dish also fits perfectly. 💛

Quality Saucepan

Use a heavy-bottomed saucepan for the cream sauce to prevent scorching. I recommend All-Clad stainless steel or enamel-coated cast iron for even heat distribution. A 3-quart pan gives you enough room to whisk without spills.

Whisk for Smooth Sauce

A sturdy stainless steel whisk is essential for creating a lump-free roux and smooth cream sauce. I keep a 10-inch ball whisk from OXO in my kitchen—it reaches all corners of the pan effortlessly.

Cheese Grater

Freshly grated cheese melts better than pre-shredded. A box grater with multiple sides works for both Gruyère and Parmesan. For speed, I use a Microplane for the Parmesan—it creates fine, fluffy shreds that melt beautifully.

Mandoline for Even Slicing

For perfectly even shallot slices, a mandoline slicer is my secret weapon. The Benriner model costs under $20 and gives you paper-thin, consistent pieces. Just be careful—those blades are razor sharp!

If you don’t have one, a sharp chef’s knife works too. 💡
