Featured Ingredients

  • Orzo: instead of using rice or a classic noodle, we’re using orzo! We love how it tastes toasted and it pairs perfectly with broccoli and cheese.
  • Fresh broccoli: make sure to use fresh broccoli florets in this recipe instead of frozen.
  • Cheddar cheese: the cheese sauce features yellow cheddar cheese, but you can swap it for white cheddar or even a cheddar blend.
  • Milk and Broth: 2% milk and broth are needed to make the sauce.
  • Garlic: garlic adds so much fresh and simple flavor to this broccoli cheese casserole recipe.

Can I substitute frozen broccoli for fresh in a casserole?

The short answer is yes you can. However frozen broccoli contains a higher water content than fresh and cooks a lot faster so your casserole may be a bit watery and the broccoli may overcook.

Tips & Notes

  • We add the broccoli later in the cooking time so it doesn’t get mushy.
  • If you still have liquid in the skillet after 6-8 minutes, leave the skillet uncovered for a few minutes so the liquid can cook off a bit.
