  • Total Time: 30 minutes
  • Yield: 4 servings (1½ cups each)

Ingredients

Chicken and Seasoning

  • 1 lb. chicken breast tenderloins
  • 1½ tsp salt (divided)
  • ½ tsp black pepper (freshly cracked)
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp smoked paprika

Cooking Base

  • 2 Tbsp salted butter
  • 1 Tbsp olive oil
  • 1½ cups orzo (uncooked)
  • 2½ cups chicken broth
  • 1 cup whole milk (room temperature)

Vegetables and Cheese

  • 3 cups frozen broccoli florets (roughly chopped)
  • 4 oz. cheddar cheese (shredded, about 1 cup)

Instructions

  1. Prepare Ingredients: Gather all ingredients and roughly chop the frozen broccoli florets to ensure even cooking and texture.
  2. Season Chicken: Cut chicken tenderloins into bite-size pieces. Place in a medium bowl and toss with 1 tsp salt, black pepper, garlic powder, onion powder, and smoked paprika until evenly coated.
  3. Sauté Chicken: Melt butter and olive oil in a large oven-safe skillet or broiler pan over medium heat. Add the seasoned chicken pieces and cook until fully cooked through, about 6 minutes per side or 12-15 minutes total, stirring occasionally for even cooking.
  4. Toast Orzo: Add dry orzo pasta directly to the pan with the cooked chicken and toss for about 2 minutes to lightly toast the orzo, enhancing its flavor.
  5. Deglaze Pan: Pour in chicken broth to deglaze the pan, scraping any browned bits off the bottom. Stir everything together and reduce heat to medium-low.
  6. Add Milk and Broccoli: Add the room temperature whole milk and stir to combine. Then incorporate the chopped broccoli florets. Let simmer for about 8 minutes, or until the orzo is tender and most of the liquid has been absorbed.
  7. Mix in Cheese: Stir in half of the shredded cheddar cheese into the skillet mixture for creamy richness.
  8. Prepare for Broiling: Sprinkle the remaining cheddar cheese evenly over the top, then season with the remaining salt and additional black pepper to taste.
  9. Broil Cheese: Transfer the skillet to the oven and broil on high for 3-5 minutes until the cheese is melted and bubbly. Alternatively, cover the pan with a lid and allow the cheese to melt on the stovetop if you prefer not to broil.

Notes

  • You can substitute chicken thighs or whole chicken breasts if tenderloins are not available.
  • Ensure the milk is at room temperature before adding to avoid curdling.
  • Frozen broccoli can be roughly chopped while frozen for ease.
  • If you don’t have a broiler-safe pan, carefully transfer the mixture to a baking dish before broiling.
  • For a lower-fat version, use reduced-fat cheese and milk, though the texture may be slightly different.
