Monday's chicken and broccoli is really about setting the tone for the week. Batch cook it, portion it out, and you've got high protein dinners handled through Wednesday.
Preheat your oven to 425°F, ensuring it's fully hot before cooking for even roasting.
Cut chicken breasts into bite-sized cubes and toss them with 2 tbsp olive oil, garlic powder, black pepper, and half the salt.
Slice broccoli florets into uniform sizes and mix with 1 tbsp olive oil, remaining salt, and lemon juice; this keeps roasting balanced and prevents drying.
Spread chicken and broccoli evenly on a large sheet pan, keeping them in a single layer to allow proper browning. Roast on the middle rack for 20 minutes, flipping halfway.
Check for doneness: chicken should reach 165°F internal temperature and broccoli should be bright green with slight crisp edges. Let cool slightly, portion into 4 containers for meal prep.
