Instructions

Preheat and Prepare Baking Dish

Set your oven to 350°F (175°C) and coat a 9×13 inch baking dish with softened butter. This prevents sticking and helps create a flavorful crust on the casserole edges.

Cook Rice According to Package Directions

Prepare the long grain white rice, ideally Jasmine, by following the package instructions closely to achieve fluffy, separate grains. Let it cool slightly before combining.

Steam Broccoli Florets

Steam broccoli florets until tender but still bright green. This retains nutrition and texture, preventing mushiness in the casserole.

Combine Rice and Broccoli

In a large bowl, gently fold the cooked rice and steamed broccoli together, maintaining broccoli integrity for a pleasing bite and even vegetable distribution.

Prepare Creamy Soup Mixture

In a medium bowl, whisk diced onions with cream of mushroom soup, cheddar cheese soup, whole milk, seasoned salt, garlic powder, and black pepper. This creates a smooth, flavorful binder.

Mix Soup Mixture with Rice and Broccoli

Pour the creamy mixture over the rice and broccoli, folding gently to coat all pieces evenly without mashing the broccoli.

Assemble the Casserole

Spread the combined mixture evenly into the buttered baking dish to ensure consistent cooking and browning.

Add Cheese Topping

Sprinkle shredded mild cheddar cheese generously over the top to melt into a golden, bubbly crust during baking.

Bake Until Golden and Bubbly

Bake the casserole for 30-35 minutes. Look for melted cheese that is lightly golden and bubbly around the edges to know it’s perfectly done.

Rest Before Serving

Remove from oven and let rest for 5 minutes. This allows the casserole to set slightly for clean slices and enhanced flavor melding.

You Must Know

  • Fresh or frozen broccoli both work well; cut frozen pieces to uniform, bite-sized florets for even cooking.
  • The double soup base of mushroom and cheddar soups delivers balanced creaminess and cheesy flavor.
  • Cooking the rice a day ahead will save time and improve texture as it absorbs flavors better.
  • Mild cheddar cheese melts beautifully while providing a rich but not overpowering cheese taste.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave to maintain creamy texture without drying out.

Serving Suggestions

Serve this casserole as a comforting side alongside baked or grilled chicken, roasted meats, or your favorite holiday feast. It also pairs nicely with fresh green salads for added freshness.

Professional Tips

  • Use Jasmine rice to prevent the casserole from becoming too sticky or mushy after baking.
  • For extra flavor and texture, sauté the diced onions lightly before adding to the soup mixture.
  • If preferred, substitute the cheddar cheese soup with cream of chicken or an extra can of cream of mushroom soup for a milder taste.

FAQs

Can I use fresh broccoli instead of frozen?

Yes, fresh broccoli works great. Just cut it into 1-2 inch florets and steam until tender before mixing.

What can I substitute for the cheddar cheese soup?

You can use an additional can of cream of mushroom or cream of chicken soup for a different but still delicious creamy base.

Is it possible to make this recipe gluten-free?

Check that the soups you use are labeled gluten-free, and use a gluten-free rice variety to make this casserole safe for gluten-sensitive diets.

Can I prepare this casserole ahead of time?

Yes, you can assemble it and refrigerate uncovered for up to 24 hours before baking. Add extra baking time if baking directly from the fridge.

How do I reheat the leftovers?

Reheat in the oven at 350°F until warmed through or microwave individual portions, covering loosely to maintain moisture.

Can I add other vegetables?

Absolutely. Diced carrots, mushrooms, or bell peppers sautéed before mixing add great flavor and texture variety.

What cheese alternatives work well for topping?

Cheddar-jack or colby-jack shredded cheese blends are excellent melting options that complement the casserole’s flavors.
