Grilled Sirloin with Spaghetti Squash and Edamame

Tips

Tip 1

Carving steak against the grain breaks muscle fibers for maximum tenderness; check the direction of lines and slice perpendicular.

Tip 2

Resting meat 5 minutes allows juices to redistribute throughout, preventing them from running onto the plate when cut.

Tip 3

Roast squash the day before and refrigerate strands to streamline assembly on cooking day.

Good to Know

Storage

Wrap cooled steak separately in foil; store up to 4 days refrigerated. Squash strands in sealed container up to 5 days. Reheat steak gently in 300°F oven 10 minutes; squash in skillet over medium-low heat with splash of broth.

Make Ahead

Roast squash and chill up to 24 hours. Prepare edamame mixture components in advance. Season steak 40 minutes before grilling for better browning.

Serve With

Plate while squash mixture is still warm. Serve with lemon wedges or simple green salad on the side. Pairs with red wine (Cabernet Sauvignon) or lighter reds.

Common Mistakes

Watch

Skip resting steak to avoid losing juices and serving a dry final product.

Watch

Overcrowd the grill to avoid uneven cooking and preventing proper searing.

Watch

Cut with the grain instead of against it to avoid tough, chewy meat.

FAQ

Can I cook the steak indoors instead of grilling?

Yes. Use a cast-iron skillet or grill pan over medium-high heat for 11-15 minutes, turning halfway, until internal temperature reaches 145-160°F. You'll lose char but gain convenience.

What if I don't have a gas grill or charcoal?

Use a broiler set to high, placing steak 3-4 inches from element, or a stovetop cast-iron skillet as noted above. Broiling time may be shorter; monitor closely.

How long can I keep leftovers and can I freeze them?

Refrigerate up to 4 days in separate containers. Freeze steak up to 3 months wrapped tightly; squash mixture up to 2 months. Thaw overnight in fridge and reheat gently.
