Ingredients
For baked chicken thighs and vegetables:
- Sweet potato
- Brussel sprouts
- Red onion
- Cauliflower
- Olive oil
- Parmesan cheese
- Garlic powder
- Salt and pepper
- Italian seasoning
- Chicken thighs
For parmesan tahini sauce:
- Olive oil
- Tahini
- Lemon
- Dijon mustard
- Garlic
- Parmesan cheese
- Worchestershire sauce
- Water to thin
Instructions
Preheat the oven to 400F. Line a sheet pan with parchment paper.
Pierce sweet potato with a fork multiple times along two sides and microwave for 2 minutes. Rotate the potato and microwave for an additional 2 minutes. This will help soften the potato to allow it to cook faster in the oven! The potato will be HOT! Once potato is cool, dice into 1 inch cubes.
Slice brussels sprouts, onions and cauliflower florets.
To a large mixing bowl, add diced potatoes, sliced brussel sprouts, red onion, and cauliflower florets. Drizzle with 1 tablespoon of olive oil.
In a small bowl, mix together parmesan cheese, garlic powder, black pepper, salt and italian spice blend. Sprinkle half of this mixture over the vegetables and toss to combine.
To a separate bowl, add chicken thighs, drizzle with the remaining 1 tablespoon of olive oil and the remaining spice mixture. Toss to combine.
Evenly spread the coated vegetables and chicken over the pan. Bake for about 25 minutes, until the chicken is fully cooked and no longer pink. The internal temperature should reach 165F.
While the meal is cooking, combine all of the sauce ingredients in a small bowl and whisk until smooth.
Drizzle over the sheet pan once cooked.

Top Tip
If you would rather boil your sweet potatoes to soften them, you may dice your sweet potatoes and add them to boiling water. Allow them to boil for about 5 minutes, until they are soft enough to pierce with a fork.

Add them to a salad or serve with pasta! It pairs so well with my red pepper pasta.
Cruciferous vegetables such as Brussels sprouts, broccoli and cauliflower may be harder for some individuals to digest due to their high sulfur content.

What do you do with the other half of the spices mix? It says put half on the vegetables but doesn't say what to do with the other half?

Hi Julie,
In the step where you are prepping your chicken thighs it mentions to add the remaining spice mixture!
Hopefully this helps!
