This Creamy Beef and Mushroom Rice Bake has helped me through countless busy weeks with its unbeatable comfort and effortless style. The casserole combines savory ground beef, tender mushrooms, and fluffy rice all nestled in a rich creamy sauce. Your family will be gathered around the table before you even set down the spatula.

I first whipped this up on a chilly night when groceries were sparse and have loved tweaking it ever since. Now my sister asks for the recipe every time the weather turns cold.

Ingredients

  • Ground beef: adds robust savory depth Use freshly ground from the butcher if possible for the best flavor
  • Chopped mushrooms: give earthiness and juicy texture Choose cremini for a deeper flavor or regular button for mildness
  • Diced onion: brings natural sweetness that softens as it bakes Look for a firm onion with shiny skin
  • Uncooked long grain white rice: absorbs all the flavorful sauce and gives a fluffy bite Rinse well before using to reduce starchiness
  • Low sodium cream of mushroom soup: lays the creamy foundation Try to pick one with simple ingredients
  • Beef broth: loosens the mixture while blending in umami Use homemade if you want something extra special
  • Full fat sour cream: creates extra rich luscious texture Plain Greek yogurt is a lighter swap
  • Garlic powder: brings gentle zing to keep each bite interesting
  • Salt and pepper: unlock all the savory notes
  • Shredded sharp cheddar: adds melty flavor and golden topping Use a block and shred yourself for best melt

Step-by-Step Instructions

Prep the Pan:
Grease a nine by thirteen inch baking dish to prevent sticking and for easy serving later
Brown the Beef Mixture:
In a large skillet cook ground beef mushrooms and onion on medium heat Stir often while breaking up beef Continue until beef is just browned and onions look golden and soft This usually takes about ten minutes Drain away any extra fat so your bake stays creamy not greasy
Mix Ingredients Thoroughly:
Transfer beef mixture to a big mixing bowl Add uncooked rice cream of mushroom soup beef broth sour cream garlic powder salt and pepper Stir until you see no more streaks and the mixture is even all over Taste and tweak salt and pepper if you like a bolder flavor
Assemble and Bake:
Pour the mixture into your prepared baking pan Spread evenly so the rice cooks at the same rate Cover tightly with foil to keep moisture in Bake in a preheated oven at three hundred fifty degrees for fifty to sixty minutes Check rice tenderness and make sure very little liquid remains
Finish with Cheese:
Take off the foil Sprinkle shredded cheddar cheese evenly over the top Return to oven uncovered about five minutes Let cheese melt and bubble up so you get an irresistible golden layer
Rest and Serve:
Let the casserole stand for at least three minutes before scooping This gives the creamy sauce time to thicken up

Sharp cheddar is my favorite addition because it melts into little pools of flavor With every bite memories come back of my kids sneaking spoonfuls right from the pan when they could not wait for dinner

Storage Tips

Store any leftovers in a tightly sealed container in the refrigerator for up to three days For best reheating results add a splash of broth before microwaving or oven baking so everything stays moist

Ingredient Substitutions

This bake handles many swaps when you need flexibility Ground turkey or chicken make tasty lighter options Use brown rice or even wild rice just add more broth and extend the baking time Greek yogurt can stand in for sour cream when you want a tangier lighter result

Serving Suggestions

This is a true one dish meal but I love serving it with a crisp green salad or some garlicky steamed green beans If you are feeling fancy a sprinkle of fresh parsley on top adds both color and brightness

11 115 g sharp cheddar cheese, shredded

Instructions

Step 01

Preheat oven to 175°C. Lightly grease a 33 x 23 cm baking dish to prevent sticking.

Step 02

In a large skillet over medium heat, cook ground beef, mushrooms, and onion, breaking up the beef, until browned and onions are translucent, about 10 minutes. Drain any excess fat.

Step 03

In a large mixing bowl, blend the sautéed beef mixture with uncooked rice, cream of mushroom soup, beef broth, sour cream, garlic powder, salt, and black pepper. Stir thoroughly to ensure even distribution.

Step 04

Transfer the mixture into the prepared baking dish and level the surface with a spatula.

Step 05

Cover the dish tightly with foil and bake for 50–60 minutes, or until the rice is tender and most liquid is absorbed.

Step 06

If using, remove the foil and evenly distribute the shredded cheddar over the surface. Bake uncovered for an additional 5 minutes, or until cheese is melted and bubbling.

Step 07

Allow to stand for at least 3 minutes to let the sauce thicken before serving.

Notes

  1. Substitute ground turkey or chicken for beef as desired.
  2. For brown rice, bake an extra 15–20 minutes and add more broth if necessary.
  3. Greek yogurt may replace sour cream for a lighter option.
  4. Enhance nutrition by adding bell pepper, peas, or other chopped vegetables.
  5. Taste the blend before baking to fine-tune seasoning.
  6. Rinsing rice before cooking prevents a gummy texture in the final bake.
  7. Dish can be assembled up to a day ahead and refrigerated. If baking directly from cold, add 10 minutes to the bake time.
  8. Store leftovers in an airtight container, refrigerated, for up to 3 days. Reheat in oven or microwave as needed.
