Detailed Directions and Instructions
Step 1: Preheat the Grill
Preheat your grill to medium-high heat to ensure it’s hot enough for cooking the steak and vegetables properly.
Step 2: Prepare the Spice Mixture
In a small bowl, mix together 2 teaspoons of chili powder, 1 teaspoon of ground cumin, 1 teaspoon of smoked paprika, and 3 cloves of minced garlic. Add 1 teaspoon of kosher salt and ½ teaspoon of freshly ground black pepper. This will be your seasoning blend for the steak.
Step 3: Season the Steak
Take the flat iron steak and rub the spice mixture all over the meat. Ensure it is evenly coated for the best flavor.
Step 4: Apply Oil to the Steak
Brush 1 tablespoon of canola oil onto the steak to help achieve a nice sear while grilling.
Step 5: Grill the Steak
Place the seasoned steak on the preheated grill. Cook the steak for about 4-5 minutes on one side. Flip the steak and grill for an additional 4-5 minutes, or until it reaches your desired level of doneness, particularly medium-rare.
Step 6: Let the Steak Rest
Once done, remove the steak from the grill and let it rest for 5 minutes. This resting period helps redistribute the juices within the meat.
Step 7: Prepare the Vegetables
While the steak is resting, take the red bell pepper, yellow bell pepper, and red onion. Cut the peppers into strips and the onion into wedges. In a bowl, toss these vegetables with the remaining 1½ tablespoons of canola oil. Season with salt and pepper to taste.
Step 8: Grill the Vegetables
Add the seasoned bell peppers and onion to the grill. Cook the vegetables, turning occasionally, until they are charred and tender, which should take about 6-8 minutes.
Step 9: Slice the Steak
After the steak has rested, thinly slice it against the grain. This will help in achieving tender pieces of meat.
Step 10: Serve
Arrange the sliced steak on a plate and serve it alongside the grilled bell peppers and onion.
