How do I make this casserole step-by-step?
Making this casserole is straightforward and takes just a bit of time. Here’s how you do it:
- Preheat oven to 350°F (175°C).
- Melt the butter in a large pot over medium heat. Once melted, add the diced onions and sauté them until softened, about 5 minutes.
- Stir in the cream of mushroom soup, milk, sour cream, garlic salt, salt, mustard powder, Italian seasoning, and pepper to combine thoroughly.
- Add in 1 cup of shredded cheddar cheese to the warm mixture and stir until it’s melted and creamy.
- Fold in the frozen broccoli and mixed vegetables, allowing them to incorporate and heat through. Remove the pot from the heat and let cool slightly.
- Once cooled, mix in the whisked eggs and cooked rice until everything is well combined.
- Transfer the mixture to a lightly greased 9 x 13 inch casserole dish and sprinkle the remaining cheddar cheese on top.
- Cover the dish with foil and bake for 20 minutes. While it bakes, mix the crushed Ritz crackers with the melted butter.
- After 20 minutes, remove the foil, sprinkle the cracker mixture over the top, and bake uncovered for another 10 minutes until golden brown.
- Remove from the oven and serve warm.
Helpful cooking tips
- For the best flavor, make sure to sauté the onions until they are translucent and fragrant.
- If using fresh vegetables instead of frozen, ensure they are cooked before adding to the mixture to avoid excess moisture.
- Keep an eye on the casserole during the last few minutes of baking to prevent the topping from burning.
How should I serve it?
This casserole pairs excellently with roasted meats or can be the centerpiece of your vegetarian meal. A simple side salad and some crusty bread can complement it nicely, creating a balanced dinner plate.
Can I make it ahead? How do I store and reheat it?
Yes, this casserole is excellent for meal prep! You can prepare it a day ahead, cover it, and store it in the fridge until you’re ready to bake. It can also be frozen before baking; just make sure to thaw before cooking. Refrigerate leftovers within 2 hours; reheat until steaming hot.
How do I fix common issues?
If your casserole turns out dry, consider adding a bit more milk or sour cream next time to enhance creaminess. If it’s bland, infuse more spices or cheese for greater flavor depth. If the rice clumps together, ensure it’s fully cooked and cool before mixing into the dish.
What variations can I try?
You might try adding different vegetables, such as spinach, bell peppers, or even corn for a sweet twist. Alternatively, spice it up by including some diced jalapeños for a bit of heat (optional). Each variation brings a unique twist to the dish!
FAQs

Yes! The casserole is already vegetarian-friendly with the use of mushrooms and cheese. Just ensure to double-check your cream of mushroom soup ingredients.
What cheese works best?
While cheddar is delicious, you can use Monterey Jack or even Gouda for a richer flavor.

Is it gluten-free?
To make it gluten-free, use a gluten-free version of the cream of mushroom soup and substitute regular Ritz crackers with gluten-free crackers.
