Ingredients

  • Fresh broccoli florets: for vibrant color and crunch choose firm deep green heads with tight buds for best flavor
  • Uncooked long grain white rice: for fluffiness use a trusted brand and inspect for even grains
  • Vegetable or chicken broth: boosts flavor quality broth rich in aroma will make a noticeable difference
  • Heavy cream: for creamy richness look for fresh cream with no off smell
  • Sharp cheddar cheese: adds tang and melt look for a block and grate it yourself for best meltability
  • Sour cream: for tangy depth a full fat sour cream will make the sauce velvety
  • Garlic powder: for background savoriness pick a brand with a garlicky punch not bitterness
  • Onion powder: for mellow sweetness a fine powder with a light yellow tint works well
  • Dijon mustard: brings brightness and a little zing choose a brand with a smooth pour and balanced tang
  • Black pepper: for mild heat freshly cracked always brings out most flavor
  • Salt: to elevate all flavors opt for fine sea salt for even seasoning
  • Breadcrumbs: add a golden crunch on top use day old bread or panko for extra texture
  • Olive oil or melted butter: mixes with crumbs for crispiness go with a neutral olive oil or unsalted butter
  • Fresh parsley: adds color and a pop of freshness choose crisp green leaves no wilting

Prepare the Broccoli:
Bring a pot of water to a boil Add chopped broccoli florets and blanch for two to three minutes until just tender and bright green Immediately drain and rinse with cold water to stop cooking This ensures broccoli is crisp not mushy
Combine Rice and Broccoli:

Cheddar cheese remains the star for me The extra sharp variety melts perfectly and brings a depth of flavor that balances the mild creaminess On holidays my little cousin always sneaks the crispy topping before we sit down to eat so someone always has to guard the casserole

Storage Tips

Once cooled this casserole stores beautifully in the fridge for up to four days Cover tightly with foil or transfer to an airtight container Reheat covered in the oven for best results or use the microwave for a quick single serving You can also wrap well and freeze for up to two months Thaw overnight in the fridge before reheating so it stays creamy

Ingredient Substitutions

Brown rice works instead of white for a nuttier bite but add extra cooking time Greek yogurt can swap for sour cream if you want more protein If you are out of cream use half and half or a mix of milk with an extra spoonful of sour cream For a gluten free version use gluten free breadcrumbs or skip the topping entirely

Serving Suggestions

This casserole stands on its own but truly shines with a simple green salad on the side For extra color and heartiness add diced cooked chicken or Thanksgiving turkey right into the mix Leftovers make a great lunch just add a squeeze of lemon or a splash of hot sauce right before eating
