One sheet pan. Two components. Twenty-five minutes in the oven. This is the meal prep recipe that earns a permanent spot in the rotation — because when you need a week of high protein lunches and you have 30 minutes, this delivers every time without requiring you to think about it.

The buffalo chicken is made with Crystal hot sauce, grass-fed butter, a splash of apple cider vinegar, and garlic powder — a proper sugar-free buffalo sauce that's bold without being vinegar-forward. The broccoli gets tossed in a homemade ranch seasoning (parsley, chives, garlic powder, onion powder, dill, salt, and pepper) and roasts alongside the chicken on the other half of the pan. One hour of prep on a Sunday = four containers of lunch ready to grab all week.

Ingredients

FOR THE BUFFALO CHICKEN

1 lb boneless skinless chicken thighs — see the chicken discussion below
2/3 cup Crystal Hot Sauce
1/2 cup unsalted grass-fed butter, melted
2 teaspoons Bragg's Raw Organic Apple Cider Vinegar
1/4 teaspoon garlic powder
1/2 teaspoon salt
Optional: a few dashes of cayenne pepper for extra heat

FOR THE RANCH BROCCOLI

10 oz broccoli florets
1 tablespoon avocado oil
2 tablespoons dried parsley
1 tablespoon dried chives
2 teaspoons garlic powder
2 teaspoons onion powder
1 teaspoon dried dill
1 teaspoon salt
1 teaspoon black pepper

Why Crystal Hot Sauce?

Crystal is less vinegar-forward than Frank's RedHot, which is the most common buffalo sauce base. The flavor is rounder and more pepper-forward, which means you taste buffalo and butter rather than vinegar. If you can't find Crystal, Frank's works — use slightly less than the recipe calls for since Frank's is more acidic. Louisiana Hot Sauce is another good substitute at the same quantity as Crystal.

Chicken Breast vs Chicken Thighs — Which to Use

Chicken thighs (recommended). This recipe was written with thighs and they're the better choice for two reasons: the fat keeps them moist at 405°F without drying out, and they stay juicy when reheated from the fridge all week. The buffalo sauce also penetrates thighs more effectively because of the slightly looser muscle fiber.

Chicken breasts. Work fine but are more sensitive to overcooking. If using breasts, pound them to an even 3/4-inch thickness before cubing so they cook evenly. Check at 12-13 minutes rather than the full 15-17. They're a higher protein, lower fat option if you're tracking macros precisely.

The Sugar-Free Buffalo Sauce

Making buffalo sauce from scratch takes 2 minutes and is significantly better than any bottled option because you control exactly what goes in it. Here's the breakdown:

Combine. In a bowl, whisk together the hot sauce, melted butter, apple cider vinegar, garlic powder, salt, and cayenne (if using).
Taste. It should be spicy, rich, and slightly tangy. Add more hot sauce for heat, more butter for richness, more vinegar for tang.
Toss the chicken. Cut chicken thighs into 1-1.5 inch cubes, then toss in the sauce until every piece is coated. Don't marinate for hours — the acid in the hot sauce will start to break down the texture. Toss and cook within 30 minutes.

The role of butter in buffalo sauce

Buffalo sauce is essentially a vinegar-based hot sauce emulsified with butter. The butter does two things: it mellows the acid and creates that rich, coating consistency that makes buffalo sauce cling to the chicken. Grass-fed butter [affiliate link] has a cleaner, slightly richer flavor. If you want dairy-free, substitute ghee — the flavor is nearly identical.

The Homemade Ranch Broccoli

The ranch seasoning blend in this recipe is worth saving as its own standalone recipe — it's excellent on any roasted vegetable, as a dip seasoning mixed into Greek yogurt, or as a general all-purpose seasoning blend.

For the broccoli: toss the florets in 1 tablespoon of avocado oil until coated. Combine all the ranch seasoning ingredients in a small bowl, then sprinkle 1.5 tablespoons of the blend over the broccoli and toss again. (Save the remaining ranch seasoning in a small jar — it keeps for months.)

Step-by-Step Instructions

Preheat and prep. Preheat oven to 405°F. Line a sheet pan with foil and spray with avocado oil cooking spray. Foil is important — the buffalo sauce burns onto an unlined pan and is very hard to clean.
Make the buffalo sauce. Whisk together all buffalo sauce ingredients in a medium bowl.
Cube and toss the chicken. Cut chicken into cubes and toss in the buffalo sauce until evenly coated. Spread on one half of the sheet pan in a single layer — don't crowd.
Season the broccoli. Toss broccoli in avocado oil. Mix ranch seasoning, sprinkle 1.5 tablespoons over the broccoli and toss again. Spread on the other half of the sheet pan.
Bake. Bake at 405°F for 15-17 minutes. The chicken should reach 165°F internal temperature and the edges should look slightly caramelized. The broccoli should be tender with some color on the edges.
Portion for meal prep. Divide evenly between 4 glass meal prep containers [affiliate link]. Let cool before sealing if possible.

Vegetable Variations

The ranch seasoning works on almost any vegetable that roasts well. Here are the best swaps:

Cauliflower florets — same prep as broccoli, same time
Green beans — trim and toss, roast 12-15 minutes
Asparagus — trim, toss, roast 10-12 minutes; check earlier
Zucchini — cut into half-moons, roast 12-15 minutes; expect some moisture release
Bell peppers — strips work well, 15-17 minutes
Brussels sprouts — halved, roast 20-22 minutes at the same temp

Sheet pan tip

Keep the chicken and vegetables separate on the pan — chicken releases juices during cooking and if the broccoli is touching the chicken, it will steam instead of roast. Leave a visible gap between the two sections.

Meal Prep and Storage

This is purpose-built for meal prep. Here's how to make it work all week:

Make on Sunday: prep, bake, portion into 4 glass containers [affiliate link]. Takes 30 minutes total.
Refrigerator: 4 days in airtight containers. The buffalo chicken holds up better than most meal prep proteins because the fat in the sauce keeps it moist.
Reheating: microwave 90 seconds. Add a fresh splash of hot sauce before reheating if you want the heat to pop more.
Freezer: freeze the chicken portion only (not broccoli — it becomes mushy). Freeze up to 3 months. Thaw overnight, reheat in microwave or skillet.

Frequently Asked Questions

Can I use a different hot sauce?

Yes — any vinegar-based hot sauce works. Frank's RedHot is the most common substitution (slightly more vinegar-forward, reduce to 1/2 cup). Louisiana Hot Sauce is very similar to Crystal. Tabasco is much hotter and more acidic — use 1/3 cup maximum. Avoid sriracha as the base sauce — it's thicker and sweeter and doesn't create the same buffalo flavor.

How do I make this spicier?

Add cayenne pepper to the buffalo sauce (a few dashes to 1/4 teaspoon depending on preference), or double down on the hot sauce and reduce the butter slightly. Finish the finished meal prep containers with red pepper flakes when serving.

Can I make this without butter?

For dairy-free: substitute ghee (same quantity) — the flavor is nearly identical. Coconut oil technically works but creates a slightly different flavor profile. Vegan butter works but can separate in the oven.

What's the protein per serving?

19.2g protein per serving from the chicken. Full macros: 425 calories, 34.8g fat, 3.7g net carbs, 19.2g protein. If you use chicken breasts instead of thighs, protein increases to approximately 27-28g per serving and fat drops significantly.

Can I make this with chicken wings instead of pieces?

Yes — toss whole wings in the buffalo sauce and bake at 425°F for 25-30 minutes, flipping halfway. This becomes a standalone wing recipe rather than a meal prep bowl, but it's excellent.
