Ingredients Section
- 30 oz Broccoli Florets: Fresh is best for that perfect crunch, but if you must use frozen, ensure they are thoroughly thawed and drained to avoid a watery gratin.
- 1 Cup Uncooked Long-Grain White Rice: This variety stays fluffy and distinct; avoid instant rice as it might turn to mush during the baking process.
- 1 Cup Buttermilk or Whole Milk: Use whole milk for a richer, creamier sauce that binds everything together beautifully.
- 1/2 tsp Freshly Ground Black Pepper: Freshly ground pepper adds a nice, sharp kick that cuts through the creaminess of the dish.
- 1/2 tsp Poultry Seasoning: This is the secret weapon that adds a savory depth often missing in simple rice dishes.
- 2 tsp Salt: Essential for bringing out the flavors of the broccoli and the cream sauce.
- 10 oz Condensed Cream of Mushroom Soup: Acts as the velvety base for our sauce; don’t skip this classic ingredient!
- 5 Cups Water: Used for boiling the rice to the perfect tenderness before baking.
- 1/2 tbsp Unsalted Butter: Adds a touch of richness to the rice water and prevents sticking.
Note: This recipe yields approximately 10 servings, making it perfect for large family gatherings or meal prepping for the week.

How to Make Uncle Ben’s Broccoli Rice Au Gratin Recipe?
Making this dish is a straightforward process that rewards you with incredible flavor. It essentially involves three main phases: cooking your base grains, creating a rich sauce, and baking it all to meld the flavors together. Don’t be intimidated by the steps; it’s a very forgiving recipe that comes together beautifully.
Cook the Rice and Broccoli Base
Start by getting your rice perfectly tender, as this forms the foundation of the casserole. In a large pot, combine your water, butter, salt, pepper, and the uncooked rice. Bring this mixture to a rolling boil, then reduce the heat to low, cover tight, and let it simmer for about 15 minutes. You want the water absorbed and the rice soft. Once the rice is done, gently fold in your broccoli florets with a fork so they distribute evenly without mashing the rice grains.
Prepare the Creamy Mushroom Sauce
While your rice is cooking or resting, turn your attention to the flavor powerhouse of this dish: the sauce. In a separate saucepan, whisk together the condensed cream of mushroom soup, milk, poultry seasoning, and a pinch of salt. Place this over medium heat and bring it to a gentle boil. Lower the heat immediately and let it simmer for about 5 minutes. You are looking for the sauce to thicken slightly so it can coat the back of a spoon, ensuring it clings to the rice later.
Assemble and Bake the Gratin
Now comes the exciting part where everything joins forces in the baking dish. Preheat your oven to 350°F (175°C) and grease your 9×13 baking dish with a little butter to prevent sticking. Spread your rice and broccoli mixture into the dish in an even layer. Pour that luscious mushroom sauce all over the top, using a spatula to spread it to the corners. Bake this uncovered for 25 to 30 minutes. You want to see the edges bubbling and the top turning a lovely golden brown before taking it out.
Additional Tips for Making this Recipe Better
- Toast the Rice: I sometimes sauté the dry rice in the butter for 2-3 minutes before adding water; it adds a nutty flavor that really deepens the final taste.
- Fresh Herbs: I love sprinkling fresh parsley or thyme into the sauce while it simmers because dried herbs just can’t compete with that pop of fresh greenery.
- Broiler Finish: For a crispy top layer, I usually turn on the broiler for the last 2 minutes of cooking, but watch it closely so it doesn’t burn!
- Let it Rest: I learned the hard way that cutting into it immediately makes it runny; let it sit for 10-15 minutes so the sauce sets up perfectly.
How to Serve Uncle Ben’s Broccoli Rice Au Gratin Recipe?
This casserole is incredibly versatile and shines as a comforting side dish.
- Plating: Serve a generous square on a warm plate, ensuring you get a good mix of the crispy top and creamy center.
- Garnishes: A sprinkle of fresh chopped chives or green onions adds a bright pop of color and a fresh bite that contrasts well with the rich sauce.
- Pairings: It pairs exceptionally well with roasted chicken, grilled steak, or pork chops. The creamy texture complements savory meats perfectly.
- Texture Contrast: Serve it alongside a crisp green salad with a vinaigrette dressing to cut through the richness of the gratin.
