Your journey into crafting the perfect Steak Alfredo with Roasted Garlic Spaghetti begins with these high-quality ingredients. Get ready to savor every creamy bite! Step‑by‑Step Instructions for Steak Alfredo with Roasted Garlic Alfredo Spaghetti Step 1: Roast the Garlic Preheat your oven to 400°F (205°C). Wrap whole garlic bulbs in foil, drizzling them with a tablespoon of olive oil to enhance their sweetness. Place in the oven and roast for about 20 minutes or until the cloves feel soft when pressed. The delicious aroma will fill your kitchen, setting the stage for your Steak Alfredo with Roasted Garlic Alfredo Spaghetti. Step 2: Cook the Spaghetti While the garlic is roasting, bring a large pot of salted water to a boil. Add your spaghetti and cook according to package instructions until al dente, usually 8-10 minutes. Once cooked, reserve about a cup of the pasta water before draining the spaghetti. Keep the hot pasta close as it will soon be enveloped in that creamy Alfredo sauce. Step 3: Sear the Steak Pat your steak dry with paper towels and season generously with salt and pepper. Heat a skillet over medium-high heat, adding 2 tablespoons of olive oil for searing. Once hot, add the steak and cook for about 4-5 minutes per side for a perfect medium-rare. Look for a beautiful brown sear; remove from heat, let it rest, and then slice it thinly against the grain. Step 4: Make the Alfredo Sauce In the same skillet used for the steak, squeeze out the roasted garlic cloves into the pan, mashing them with a fork. Pour in the heavy cream and bring to a gentle simmer over medium heat. Whisk in the Parmesan cheese until completely melted and smooth, adjusting the seasoning with salt and pepper. This creamy base will elevate your Steak Alfredo with Roasted Garlic Alfredo Spaghetti. Step 5: Combine Everything Toss the drained spaghetti into the creamy sauce, mixing thoroughly until all strands are well-coated. If the sauce is too thick, gradually add some reserved pasta water until you reach your desired consistency. Then, gently fold in the sliced steak, allowing everything to warm up together for a couple of minutes to meld the flavors. Step 6: Serve and Garnish Plate your Steak Alfredo with Roasted Garlic Alfredo Spaghetti, creating a deliciously inviting dish. Garnish each plate with freshly chopped parsley to add a pop of color and freshness. Serve hot right from the stove, inviting everyone to dig into this comforting, low-carb creation!

Make Ahead Options These Low-Carb Steak & Roasted Garlic Alfredo Spaghetti are perfect for meal prep enthusiasts! You can roast the garlic and cook the spaghetti up to 3 days in advance; simply store the garlic in an airtight container in the refrigerator and keep the spaghetti slightly undercooked (al dente) to maintain texture. Also, you can sear the steak up to 24 hours prior, letting it rest before refrigerating. When you’re ready to serve, gently reheat the garlic, combine it with the cream, and finish the Alfredo sauce, then toss in the spaghetti and sliced steak. This ensures your dish remains just as delicious while saving precious time on busy weeknights! How to Store and Freeze Steak Alfredo Fridge: Keep any leftover Steak Alfredo with Roasted Garlic Alfredo Spaghetti in an airtight container for up to 3 days. Freezer: This dish can be frozen for up to 2 months. Store the steak and sauce separately to maintain texture, using airtight bags or containers. Reheating: When ready to enjoy, thaw overnight in the fridge and gently reheat on the stove over low heat, adding a splash of cream or reserved pasta water to rejuvenate the sauce. Avoid Texture Loss: To prevent the sauce from thickening too much when reheating, stir frequently and heat slowly until warmed through. Expert Tips for Steak Alfredo Perfect Steak Doneness: Use a meat thermometer to check the internal temperature; aim for 130-135°F (54-57°C) for ideal medium-rare steak. Avoid Sauce Separation: When reheating the alfredo sauce, do so gently over low heat to prevent it from separating; add a splash of cream if it thickens. Warming the Steak: Gently fold the sliced steak into the sauce just before serving to keep it warm and tender without overcooking. Pasta Water Magic: Save some reserved pasta water; adding a little during mixing can help achieve that silky sauce consistency for your Steak Alfredo with Roasted Garlic Alfredo Spaghetti. Garlic Preference: If you love a stronger garlic flavor, sauté fresh garlic in olive oil before adding the roasted garlic; this adds an extra kick to your sauce.

Low-Carb Steak & Roasted Garlic Alfredo Spaghetti Recipe FAQs How do I select ripe garlic for roasting? When choosing garlic for roasting, look for bulbs that are firm with no soft spots or sprouts. The skin should be tight and dry. Ideally, pick bulbs that feel heavy for their size; this indicates freshness. A good garlic bulb will have a strong, pungent aroma—perfect for enhancing your Alfredo sauce! What’s the best way to store leftovers? Store any leftover Steak Alfredo with Roasted Garlic Alfredo Spaghetti in an airtight container in the refrigerator for up to 3 days. This keeps the flavors fresh while preventing drying out. To enjoy it later, simply reheat gently on the stovetop, adding a splash of cream or reserved pasta water if needed to moisture the sauce! Can I freeze this dish? Absolutely! You can freeze Steak Alfredo with Roasted Garlic Alfredo Spaghetti for up to 2 months. I recommend storing the steak and sauce separately in airtight containers. When you’re ready to enjoy, thaw overnight in the refrigerator before reheating on low heat to maintain the texture and flavor. What should I do if my sauce is too thick? If your alfredo sauce becomes too thick, don’t fret! Simply add a little bit of the reserved pasta water or some extra cream while gently stirring over low heat until it reaches your desired consistency. This will restore its creamy texture without sacrificing flavor. Are there dietary considerations for this recipe? Indeed! This recipe offers low-carb and dairy-free options. If you’re making it dairy-free, substitute heavy cream with coconut cream and use nutritional yeast in place of Parmesan. For those with gluten sensitivities, swapping traditional pasta for zoodles or shirataki noodles makes it suitable for a keto diet as well! How can I avoid overcooking the steak? To ensure your steak is perfectly cooked, always use a meat thermometer. For medium-rare, aim for an internal temperature of 130-135°F (54-57°C).
