Dive into this Garlic Butter Steak with Brussels Sprouts and Butternut Squash recipe and savor the seasonal flavors! Step‑by‑Step Instructions for Garlic Butter Steak with Brussels Sprouts and Butternut Squash Step 1: Preheat your oven Begin by preheating your oven to 400°F (200°C). This temperature is perfect for roasting, ensuring that your Brussels sprouts and butternut squash will develop a lovely caramelization. While the oven warms up, gather your ingredients and prepare your baking sheets with parchment paper for easy cleanup. Step 2: Prepare the vegetables Next, take your butternut squash and carefully cube it into bite-sized pieces. For the Brussels sprouts, rinse them, trim the ends, and halve them for even roasting. Toss both the cubed squash and halved sprouts separately with olive oil, salt, and pepper in mixing bowls. This will ensure they’re well-coated and flavorful for your Garlic Butter Steak with Brussels Sprouts and Butternut Squash. Step 3: Roast the vegetables Spread the prepared Brussels sprouts and butternut squash on separate parchment-lined baking sheets in a single layer. Place the squash in the oven first, allowing it to roast for about 30 minutes. After 10 minutes, add the Brussels sprouts to the oven and roast everything together, flipping the vegetables once halfway through for even cooking. Both should be tender with a golden finish when done. Step 4: Season the steak While the vegetables roast, move on to your flank steak. Pat it dry with paper towels to help achieve a nice sear. Rub the steak generously with smoked paprika, chili powder, salt, and pepper on both sides. This seasoning mix will enhance the flavors of the Garlic Butter Steak, giving it that delicious kick you crave. Step 5: Sear the steak Heat a cast-iron skillet over medium-high heat for about 2 minutes. Once hot, add a splash of olive oil to coat the bottom. Place the flank steak in the skillet and sear it for approximately 5 minutes on each side for a perfect medium-rare. Look for a beautiful brown crust to form, which will lock in the juices and flavors. Step 6: Rest & slice the steak After searing, remove the skillet from the heat and transfer the steak onto a cutting board. Allow the flank steak to rest for about 5 minutes; this step helps the juices redistribute for a juicier bite. Once rested, slice the steak against the grain into 1-inch strips, ensuring tenderness with each piece you serve. Step 7: Prepare the garlic butter In the same skillet, melt a generous tablespoon of high-quality butter over medium heat, scraping up any flavorful bits. Add minced garlic and cook for 1-2 minutes, stirring frequently until the garlic is fragrant but not browned. This garlic butter will elevate your Garlic Butter Steak and tie the dish together with rich flavor. Step 8: Combine the flavors Return the sliced flank steak to the skillet with the garlic butter and toss gently, adding fresh thyme to infuse an earthy aroma. Coat each piece of steak with the fragrant garlic butter sauce, allowing the flavors to meld for a couple of minutes over gentle heat. Step 9: Serve the dish Finally, add your beautifully roasted Brussels sprouts and butternut squash back into the skillet with the steak just to warm them through. Serve immediately on a platter, showcasing the vibrant vegetables alongside the glazed steak. Your Garlic Butter Steak with Brussels Sprouts and Butternut Squash is ready to impress! Garlic Butter Steak with Variations Feel free to add your personal touch to this comforting dish, making it uniquely yours! Vegetable Swap: Replace Brussels sprouts with broccoli or asparagus for a different crunch. Both options beautifully complement the rich, savory steak. Grain Addition: Incorporate wild rice or quinoa for a heartier meal. The nutty flavor and chewy texture add depth and satisfaction to your plate. Spice It Up: Add a pinch of cayenne pepper to your garlic butter for an extra kick. This twist elevates the dish, appealing to those who love a hint of heat. Different Cuts: Experiment with ribeye or sirloin steak instead of flank steak. Each cut brings its unique juicy tenderness and flavor profile to the table. Herb Twist: Swap fresh thyme for fresh rosemary to create an aromatic flair in your garlic butter. Rosemary provides a robust flavor that pairs beautifully with the garlic. Maple Infusion: Drizzle a touch of maple syrup over the butternut squash before roasting. This adds a hint of sweetness, balancing the savory elements of the dish.

Garlic Butter Flank Steak with Roasted Brussels Sprouts and Butternut Squash Recipe FAQs What kind of flank steak should I use? Absolutely! Flank steak is the main protein for this dish because it absorbs flavors wonderfully. If you can’t find flank steak, skirt or hanger steak are great alternatives that also provide tenderness and flavor. How do I know when my vegetables are properly roasted? Very! Your butternut squash should be tender and caramelized after roasting for about 30 minutes, while the Brussels sprouts will need approximately 20-25 minutes. Look for a golden finish with a slight crisp on the outside. Flipping them halfway through ensures even cooking. What is the best way to store leftovers? I recommend placing any leftovers in an airtight container and storing them in the fridge for up to 3 days. This method helps maintain their moisture and flavors. Just be sure to cool them down to room temperature before sealing the container! Can I freeze Garlic Butter Steak with Brussels Sprouts and Butternut Squash? Absolutely! For longer storage, you can freeze the steak and vegetables in a freezer-safe container for up to 2 months. To prevent texture changes upon thawing, separate the steak from the vegetables before freezing. When you’re ready to enjoy, simply thaw in the refrigerator overnight and reheat gently in a skillet to avoid drying out the meat. Are there any dietary considerations I should keep in mind? Yes! Always be cautious regarding allergens. This recipe contains butter, which is a dairy product, so it’s not suitable for those with dairy allergies. If preparing for pets, avoid sharing this meal with them, as garlic can be harmful to dogs. What if my steak turns out tough? Very unfortunate! If you find your steak is tough, it could be due to cooking it too long or not slicing against the grain. Always aim for medium-rare at about 130°F, and let the steak rest before slicing. When slicing, cut against the grain for a more tender bite. If the steak is already cooked and tough, try using a meat tenderizer and marinating it overnight in your favorite marinade for extra tenderness next time!
