High Protein Low Carb Meal Prep: Lemon Oregano Chicken

• One sheet pan handles the chicken and broccoli while cauliflower rice cooks separately, which prevents the rice from turning watery under the vegetables.
• Boneless thighs bring more richness than breast meat, while lemon, oregano, feta, and olives make cold or reheated portions feel intentionally seasoned.
• Four identical containers simplify portioning, yet dressing is packed separately so vegetables retain their edges until lunch.
• Use this as a base format: change the vegetable or garnish, but keep the chicken portion and cooking order consistent for planning.

• 1 1/2 pounds boneless, skinless chicken thighs, cut into 2-inch pieces (680 g)
• 2 tablespoons extra-virgin olive oil (27 g)
• 1 tablespoon dried oregano, divided (3 g)
• 1 teaspoon kosher salt (6 g)
• 1/2 teaspoon freshly ground black pepper, divided (1 g)
• 6 cups small broccoli florets, stems included (540 g)
• 4 cups frozen riced cauliflower, unthawed (680 g)
• 1 cup crumbled feta (150 g)
• 1/2 cup pitted Kalamata olives, halved (75 g)
• 1 medium lemon, zested, plus 3 tablespoons juice (120 g)

Ingredient notes

• Boneless, skinless chicken thighs stay the anchor here because their slightly richer texture suits repeated reheating. Trim obvious excess fat, then cut larger pieces in half so they roast at a similar pace and fit evenly into containers.
• Frozen cauliflower rice keeps prep short, but cook it in a wide skillet until steam has mostly escaped. Leaving it wet makes the bottom of each box loose, particularly after refrigeration and reheating.
• Use small broccoli florets with dry cut surfaces, which encourage browning instead of steaming on the pan. Keep the stems too; slice them thinly so they finish with the florets and add useful crunch.
• Block feta gives you larger salty pockets than pre-crumbled feta, though either format works in the containers. Add it after the cooked ingredients cool slightly, so it stays distinct rather than melting into the warm cauliflower rice.
• Kalamata olives bring briny depth, while lemon juice cuts through the chicken and feta without needing a heavy sauce. Choose a firm lemon and zest it before juicing; the zest carries fragrance through the boxes after chilling.

1. 1Heat and prep

   Heat the oven to 425°F and line a large rimmed sheet pan with parchment. Zest the lemon, then squeeze its juice into a small bowl. Cut chicken into even pieces, halve the olives, and keep the feta chilled while you prepare the vegetables. Set out four containers with tight-fitting lids for assembly.

2. 2Season the chicken

   Put the chicken in a large bowl with half the olive oil, oregano, lemon zest, salt, and pepper. Toss until every piece is coated, then spread it over one side of the prepared pan. Leave visible space between pieces so the surfaces can brown rather than steam during roasting.

   

3. 3Add the broccoli

   Toss broccoli with the remaining olive oil, a pinch of salt, and pepper. Arrange it on the open side of the pan in one layer. Roast chicken and broccoli for 18 to 22 minutes, stirring broccoli once halfway through, until the chicken reaches 165°F in the center.

   

4. 4Cook the rice

   While the pan roasts, heat a wide skillet over medium-high heat. Add frozen cauliflower rice and cook for 6 to 8 minutes, stirring often, until it is hot and most visible moisture has evaporated. Season lightly with salt, pepper, and one tablespoon of the lemon juice before removing from heat.

5. 5Mix the dressing

   Whisk the remaining lemon juice with oregano, pepper, and a small pinch of salt in the bowl used for zesting. Taste and adjust only after accounting for the salty feta and olives. Divide the dressing among four small containers, keeping it separate from the warm food for cleaner lunch boxes.

6. 6Portion the boxes

   Let chicken, broccoli, and cauliflower rice cool briefly before packing. Divide rice among four containers, then add broccoli and chicken in distinct sections. Scatter feta and olives over the top, seal with the dressing containers, and refrigerate. Add dressing just before eating, or toss everything together after reheating.

• Use a pan large enough to hold the chicken and broccoli without crowding. If the pan looks full before roasting, divide the ingredients between two pans rather than piling them up. The vegetables need exposed surface area for browned edges and concentrated flavor.
• Cook cauliflower rice in a wide skillet, not a deep saucepan. A broad surface lets steam escape quickly, which makes it easier to pack without pooling liquid beneath the chicken. Stir often, but let it sit briefly between stirs.
• Cool the cooked components briefly before closing the containers. This limits trapped steam, which can soften broccoli and dilute the lemon dressing. Keep feta, olives, and dressing near the top so their flavor remains noticeable in every portion.

Eat these boxes warm, at room temperature, or chilled depending on the day. For a fuller dinner plate, add a simple arugula salad dressed with extra lemon and olive oil. A spoonful of Greek yogurt mixed with lemon zest works as a creamy topping if dairy fits your plan. If you want more crunch, pack sliced radishes or cucumbers separately. Keep any bread outside the container rather than using it to stretch a portion that already has chicken, vegetables, feta, and olives.
