A super easy weeknight bake with juicy chicken, tender potatoes, and caramelized brussels sprouts all cooked together in one pan. Minimal prep, cozy flavors, and basically zero cleanup.
Get prepped: Preheat your oven to 350°F. Lightly coat a large baking dish with nonstick spray.
Layer the vegetables: Line one side of the dish with 2 cups brussels sprouts. Line the opposite side with 3 cups red potatoes.
Season and add the chicken: Season 1 to 1.5 pounds chicken breasts with salt and pepper, then place them down the center of the dish between the vegetables.
Add butter and seasoning: Scatter the 4 tablespoons butter pieces over everything. Sprinkle 1 packet Italian dressing seasoning mix evenly over the full pan.
Bake: Cover the dish tightly with foil. Bake for 45 minutes to 1 hour, until the potatoes are tender and the chicken reaches 165°F.
Notes
Let the chicken rest for a few minutes before slicing.
Cut the potatoes smaller if you want them very soft.
Uncover the last 10 minutes for browned edges.
Add a drizzle of olive oil if you want extra crispness.
If the chicken breasts are very thick, slice them horizontally so everything finishes at the same time.
