Method
Preparation
- Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.
- In a large skillet over medium heat, melt butter until it shimmers. Add the chopped onion and cook for 4–5 minutes until softened and fragrant.
- Add the ground beef and cook until browned, breaking it apart with a wooden spoon. Season with salt, pepper, and Worcestershire sauce.
- Stir in the minced garlic and cook for 30 seconds until aromatic. Add the uncooked rice and stir to coat it in the buttery, beefy mixture.
Cooking
- Pour in the beef broth and cream of mushroom soup, stirring until smooth. Fold in the frozen peas and carrots if using. Bring the mixture to a gentle simmer, cover, and cook for 12–15 minutes until the rice has absorbed most of the liquid but is still slightly firm.
- Remove the skillet from heat and stir in 1 cup of shredded cheddar until fully incorporated and creamy.
- Transfer the mixture to the prepared baking dish, top with the remaining 1/2 cup cheddar, and cover with foil.
- Bake for 15 minutes covered, then remove the foil and bake another 10 minutes until the top is bubbly and golden.
- Let rest for 5 minutes before serving.
Notes
This casserole can be assembled up to a day ahead and refrigerated before baking. Toasting the rice briefly before simmering adds a nutty depth. Letting the casserole rest after baking allows it to set and slice cleanly.
