This is the kind of weeknight dinner I lean on when life is loud and I just want something cozy without babysitting a skillet.
Everything goes into one dish, the seasoning does all the heavy lifting, and the oven takes it from there. You get juicy chicken, tender potatoes, and caramelized brussels sprouts with basically no effort and almost zero cleanup. It’s simple, comforting, and the kind of meal everyone actually eats.
Step-by-step photos and instructions are below, but you can jump right to the recipe card if you wish!

Key Recipe Ingredients
The full list of ingredients and amounts is found in the printable recipe card below.
- Red potatoes. Hold their shape and cook evenly. Yukon golds work too.
- Brussels sprouts. Choose firm sprouts. Green beans or zucchini can replace them.
- Chicken breasts. Lean and mild. Thighs are great too.
- Butter. Melts into the vegetables and chicken for a rich finish.
- Italian dressing seasoning mix. Adds classic herbs and tangy seasoning fast.
Troubleshooting Guide – Common Problems and Solutions
- Vegetables too firm. Cut smaller or bake a bit longer.
- Chicken overcooked. Check earlier in the bake.
- Too salty. Use half the seasoning packet.
- Too dry. Add a splash of broth before baking.
- Vegetables too soft. Remove foil for the last 10 minutes.

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.
