BBQ Glaze Recipe: Labor Day Flat Iron Steak Skewer Guide

This is the complete guide to the only BBQ glaze recipe you need for your Labor Day cookout: flat iron steak skewers, glazed to a sticky, caramelized finish and grilled hot and fast for the last long weekend of summer. Flat iron steak is one of the most underrated cuts for skewers — tender, beefy, and quick-cooking — and this BBQ glaze recipe is built specifically to cling to it without falling apart on the grate.

Why This BBQ Glaze Recipe Works for Flat Iron Steak Skewers

A good BBQ glaze recipe needs three things: enough sugar to caramelize, enough acid to cut through richness, and enough body to actually stick to the meat instead of dripping into the coals. Pepper jelly checks every box straight out of the jar, which is why it makes such an easy base for a BBQ glaze recipe — no simmering a sauce for an hour, no reducing anything. You warm it, brush it, and you're done.

Ingredients for This BBQ Glaze Recipe

• 1.5-2 lbs flat iron steak, cut into 1-inch cubes
• 1 red onion and 2 bell peppers, cut into skewer-sized chunks
• Wooden or metal skewers
• 1/2 cup Classic Jalapeño Spread
• 1 tablespoon apple cider vinegar and 1 tablespoon melted butter
• Salt, black pepper, and garlic powder for seasoning

How to Build and Grill Labor Day Steak Skewers

1. If using wooden skewers, soak them in water for 30 minutes so they don't scorch on the grill.
2. Season cubed flat iron steak with salt, pepper, and garlic powder, then thread onto skewers alternating with onion and bell pepper pieces.
3. Warm the Classic Jalapeño Spread with apple cider vinegar and melted butter in a small saucepan over low heat until smooth and pourable — this is your finished BBQ glaze recipe base.
4. Grill skewers over high direct heat for 2-3 minutes per side, turning to sear all sides, for a total of about 8-10 minutes for medium doneness.
5. During the final 2 minutes, brush the BBQ glaze recipe generously over the skewers, letting it caramelize slightly without burning.
6. Remove from the grill, brush on a final layer of glaze, and let the skewers rest 3-5 minutes before serving.

Customizing Your BBQ Glaze Recipe

Once you've got the base BBQ glaze recipe down, swapping spreads changes the whole personality of the dish. Jalapeño Blackberry Spread gives skewers a deep, slightly tart glaze that pairs beautifully with red onion, while Red Hot Spread turns the same technique into a fiery version for guests who like more heat on their holiday plate. If you're hosting a mixed crowd, the THE BBQ Boost 3 Pack Bundle lets you run three glaze stations at once so everyone builds their own skewer flavor.

Make-Ahead and Crowd Tips for Labor Day

Skewers are one of the best Labor Day dishes for a crowd because the prep splits cleanly into stages. Cube the steak and chop your vegetables up to a day ahead and store separately in the fridge. You can even thread the skewers themselves several hours before guests arrive, covered and chilled, so all that's left on the holiday is warming your BBQ glaze recipe and firing up the grill. For a big backyard gathering, plan on 2-3 skewers per adult alongside sides.

Serving Your Skewers

Lay finished skewers on a large platter over a bed of greens, drizzle any remaining glaze over the top, and scatter fresh herbs or a squeeze of lime for brightness. It's a dish that looks like it took far more effort than it did — perfect for sending summer off with something a little more memorable than the usual burger spread.

Frequently Asked Questions

How do I keep a BBQ glaze recipe from burning on the grill?

Because pepper jelly is sugar-heavy, any BBQ glaze recipe made from it can scorch over direct high heat if it's brushed on too early. Wait until the last few minutes of cooking to apply it, keep the heat moderate during the glazing stage, and watch closely — caramelization happens fast.

Can I make this BBQ glaze recipe ahead of time?

Yes. Warm and mix the glaze up to three days ahead and store it in a sealed jar in the fridge. Reheat gently on the stovetop or in short microwave bursts until it's pourable again before brushing it onto your Labor Day skewers.

What's the best cut of steak for skewers besides flat iron?

Sirloin and top round both work well if flat iron isn't available, though flat iron stays especially tender because of its high marbling relative to its price. Whatever cut you choose, cube it evenly so every piece cooks at the same rate.

Do I need to marinate the steak before glazing?

Marinating is optional with this BBQ glaze recipe since the glaze itself delivers plenty of flavor and moisture in the final minutes of cooking. A simple salt-and-pepper seasoning ahead of time is all the steak really needs.
