How to Make Steak with Green Sauce and Sweet Potatoes

Prepare Sweet Potatoes: Preheat your oven to 350°F. Wash and slice the sweet potatoes in half lengthwise. Rub them with olive oil, season with salt and pepper, and roast cut-side down for about 30 minutes until tender and soft.

Make Spinach Sauce: While the sweet potatoes are roasting, combine fresh baby spinach, garlic, olive oil, balsamic vinegar, cumin, chili powder, and a pinch of salt in a food processor. Blend until the mixture is smooth and vibrant; set aside.

Steak with Green Sauce and Sweet Potatoes Recipe FAQs

Very! If your steak isn’t tender, it might not have rested long enough after cooking. Make sure to let it rest for at least 5-10 minutes to allow the juices to redistribute. Additionally, remember to slice against the grain; this technique helps break up the muscle fibers for a more tender bite.
