Total Time: 40-45 mins
Servings: 4
Difficulty: Easy
Ingredients
- 1 ½ cups instant white rice (or 2 cups cooked rice)
- 2 cups fresh broccoli florets (or frozen, thawed)
- 2 tbsp butter
- 1 small onion, diced
- 1 can (10.5 oz) cream of mushroom or chicken soup
- 1/2 cup milk
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/4 tsp salt
- 1/4 tsp black pepper
- 1 cup shredded sharp cheddar cheese (divided)
- 1/4 cup crushed potato chips or breadcrumbs (optional, for topping)
- Butter or cooking spray for greasing the pan
Instructions
1. Preheat Your Omnia Oven
Place the Omnia oven base on your RV or camp stove over medium heat. Let it heat for a few minutes while you prepare the ingredients . Preheating helps ensure even cooking from the start.
2. Cook the Rice and Broccoli
If using instant rice, cook it according to the package directions or prepare it on the stovetop. If using fresh broccoli, steam or blanch it until crisp-tender (about 3-4 minutes). Pro tip: You can also cook the broccoli and rice together—bring 3 cups of water to a boil, add broccoli and rice, and cook for 7 minutes over high heat, stirring occasionally . Drain any excess water.
3. Sauté the Onion
In a small skillet on your camp stove, melt the butter over medium heat. Add the diced onion and cook for 3-4 minutes until softened and translucent. The gentle heat of the stovetop brings out the onion’s natural sweetness.
4. Make the Sauce
In a medium bowl, whisk together the cream of mushroom or chicken soup, milk, garlic powder, onion powder, salt, and pepper . Stir in half of the shredded cheese (about 1/2 cup) until the sauce is smooth and creamy .
5. Combine Everything
In a large bowl, mix the cooked rice, broccoli, sautéed onion, and the cheese sauce until everything is evenly coated.
6. Assemble in the Omnia Pan
Generously grease the Omnia baking pan with butter or cooking spray to prevent sticking. If you have the Omnia silicone liner, place it in the pan for even easier cleanup. Transfer the casserole mixture to the pan and spread it evenly. Top with the remaining 1/2 cup of shredded cheese. For extra crunch, sprinkle with crushed potato chips or breadcrumbs .
7. Bake to Perfection
Place the pan onto the preheated Omnia base and cover with the lid. Bake over low to medium-low heat for 30-35 minutes. Important: The Omnia can be hotter at the bottom than the lid thermometer suggests, so keep the heat moderate to prevent burning . The casserole is ready when the cheese is melted, bubbly, and starting to turn golden.
8. Rest and Serve
Remove the Omnia from the heat and let the casserole rest for 5 minutes. This allows it to set and makes it easier to serve. Serve warm as a side dish or a complete meal.
Tips for Perfect Omnia Oven Cheesy Broccoli Rice Casserole
Temperature Control on Your Camp Stove
One key to success with the Omnia oven is managing the heat. It can be hotter at the bottom compared to the top, so it’s often better to cook at a lower temperature for a longer time to prevent burning . Start with medium heat to get the oven up to temperature, then reduce to low or medium-low to maintain a steady bake.
Using the Omnia Silicone Liner
Using the Omnia silicone liner makes cleanup incredibly easy and prevents sticking . If you don’t have the liner, simply grease the Omnia baking pan generously with butter or cooking spray. Important note: The silicone liner holds slightly less than the metal pan, so don’t overfill it .
Customizing Your Casserole
This recipe is incredibly versatile. You can swap the cream of mushroom soup for cream of chicken, celery, or a homemade sauce . Feel free to add cooked, shredded chicken to make it a heartier main dish . You can also add other vegetables like cauliflower, peas, or mushrooms .
Vegetarian Version
For a vegetarian version, simply use cream of mushroom or celery soup instead of chicken soup. It’s just as delicious and satisfying.
Variations to Try
Chicken Broccoli Rice Casserole
Add 1 ½ cups of cooked, shredded chicken to the casserole mixture before baking. This transforms it into a hearty main dish that’s perfect for dinner .
Cauliflower and Broccoli Casserole
Swap half the broccoli for cauliflower florets. The combination of the two vegetables adds variety in both color and flavor.
Extra Cheesy Casserole
Use a mix of cheddar, Monterey Jack, and Parmesan for a more complex cheesy flavor. A little smoked paprika adds a subtle smoky kick.
Crispy Onion Topping
For an extra crunchy topping, use crushed potato chips or crispy fried onions instead of breadcrumbs. The salty crunch is a perfect complement to the creamy casserole.
Brown Rice Version
For a whole-grain twist, use instant brown rice. Brown rice is an excellent way to eat more whole grains and adds a nutty flavor to the casserole .
Storage Instructions
Storing Leftovers
Place leftover casserole in an airtight container and refrigerate within 2 hours. It will stay fresh in your camper fridge for up to 5 days .
Reheating Without Drying Out
The best way to reheat is back in the Omnia oven over low heat for 10-15 minutes until warmed through. You can also reheat individual portions in a skillet over medium heat with a splash of milk to restore creaminess.
Freezing for Future Trips
This casserole freezes well for up to 3 months. Place it in a freezer-safe container and thaw in your RV refrigerator overnight before reheating in the Omnia oven .
