• 1 lb lean ground beef – Provides a rich, meaty base.
• 1 onion, diced – Adds depth of flavor.
• 1 clove garlic, minced – Enhances the savory taste.
• 1 can (8 oz) sliced mushrooms, drained – Adds texture and umami flavor.
• ½ tsp dried oregano – Brings a warm, herby aroma.
• 10 oz frozen chopped spinach, thawed and squeezed dry – A nutritious veggie boost.
• 1 cup instant rice – Quick-cooking and absorbs flavors beautifully.
• 1¼ cups water – Helps cook the rice perfectly.
• 1 can (10.5 oz) condensed cream of celery soup – Adds creaminess and flavor.
• ⅓ cup sour cream – Enhances the creamy texture.
• Salt & pepper, to taste – Balances the flavors.
• ½ cup frozen mixed vegetables – Adds variety and extra nutrients.
• 1 cup shredded mozzarella cheese – The cheesy topping that makes everything better.

Step-by-Step Instructions

Step 1: Preheat the Oven

Before you begin assembling your casserole, preheat your oven to 350°F (175°C). Greasing a 9×13-inch baking dish will prevent sticking and make serving easier.

Step 2: Cook the Ground Beef

In a large skillet, heat a drizzle of oil over medium heat. Add the ground beef, diced onion, and minced garlic, cooking until the beef is browned and no longer pink. Stir frequently to break up the meat and ensure even cooking. Once done, drain any excess fat to keep the casserole from becoming greasy.

Step 3: Combine the Ingredients

In a large mixing bowl, combine the cooked beef mixture with the drained mushrooms, oregano, spinach, instant rice, water, cream of celery soup, sour cream, frozen mixed vegetables, salt, and pepper. Stir everything together until well combined.

Step 4: Assemble the Casserole

Pour the mixture into the prepared baking dish, spreading it out evenly. Cover the dish tightly with foil to trap steam and ensure the rice cooks properly.

Step 5: Bake Until Perfection

Place the covered casserole in the preheated oven and bake for 40-45 minutes, until the rice is tender and the flavors have melded together.

Step 6: Add Cheese & Broil

Remove the foil and sprinkle shredded mozzarella cheese evenly over the top. Return the dish to the oven and broil for 3-5 minutes until the cheese is melted, golden, and bubbly.

Step 7: Let It Rest & Serve

Let the casserole rest for 5-10 minutes before serving. This allows the flavors to settle and makes slicing easier. Enjoy!

How to Serve Hamburger & Rice Casserole

One of the best things about this Hamburger & Rice Casserole is how versatile and satisfying it is on its own, but you can also pair it with a few side dishes to create a well-rounded meal. Since this dish is already packed with protein, vegetables, and carbs, you don’t need much to complement it. However, adding a fresh or crunchy element can help balance the creamy and cheesy flavors of the casserole.

Serving Ideas:

• With a Fresh Green Salad: A simple side salad with crisp lettuce, cherry tomatoes, cucumbers, and a light vinaigrette helps cut through the richness of the casserole. It adds a refreshing contrast that balances the dish.
• With Roasted or Steamed Vegetables: If you want to boost the veggie content, serve the casserole with steamed broccoli, roasted carrots, or sautéed green beans. These sides enhance the nutritional value while keeping the meal hearty and wholesome.
• With Garlic Bread or Dinner Rolls: A warm slice of buttery garlic bread or soft dinner rolls makes this meal feel even more comforting. You can use them to soak up any extra creamy sauce from the casserole.
• With a Side of Pickles or Coleslaw: The tanginess from pickles or a light coleslaw provides a nice contrast to the richness of the dish. A vinegar-based coleslaw is especially great for adding some acidity.
• Topped with Extra Cheese and Herbs: For an extra indulgent touch, sprinkle some Parmesan cheese and chopped fresh parsley on top just before serving. This adds both flavor and a pop of color.

Refrigerator:

Store any leftovers in an airtight container and keep them in the fridge for up to 3–4 days.

Frequently Asked Questions (FAQ)

1. Can I Make This Casserole Ahead of Time?

Yes! You can prepare the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. Simply cover it tightly with foil or plastic wrap, then bake as directed when you’re ready to eat. If baking straight from the fridge, add an extra 5-10 minutes to the baking time.

2. Can I Use Fresh Rice Instead of Instant Rice?

Absolutely! If using fresh rice, cook 1½ cups of white or brown rice in advance, then mix it into the casserole. Reduce the water in the recipe to ½ cup since the rice is already cooked.

3. What’s the Best Way to Store Leftovers?

Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Make sure to let the casserole cool completely before storing to maintain the best texture.

4. Can I Freeze This Casserole?

Yes, this casserole is freezer-friendly! After it has cooled completely, transfer it to a freezer-safe container or divide it into portions and store in resealable freezer bags. It will keep well in the freezer for up to 3 months. Thaw overnight in the refrigerator before reheating.

5. How Do I Reheat This Casserole?

• Oven: Cover with foil and bake at 350°F (175°C) for 15-20 minutes until heated through.

Of course! While mozzarella cheese gives the casserole a mild and gooey texture, you can experiment with cheddar, Monterey Jack, pepper jack, or even a blend of cheeses for a different flavor profile.

10. Can I Use Fresh Vegetables Instead of Frozen?

Yes, fresh vegetables can be used instead of frozen! Just dice them into small pieces so they cook evenly. If using fresh spinach, sauté it for 1-2 minutes before adding it to the mixture to prevent excess moisture.
