How to Make Garlic Butter Steak Bites & Zucchini – Easy Low Carb Dinner Recipe
Step 1: Prep and Season Your Steak
Start by taking the steak out of the fridge about 15 to 20 minutes before cooking. This allows it to come to room temperature for even cooking. Pat the beef cubes dry with paper towels—it’s an important step that helps achieve a beautiful sear. Generously season the meat with coarse sea salt and freshly cracked black pepper, and if you like, add a sprinkle of onion powder and smoked paprika to elevate flavor complexity.
Step 2: Chop Zucchini and Mince Garlic
While your steak is resting, prep your veggies. Chop zucchini into uniform half or quarter moons so they cook evenly, and mince fresh garlic finely so the butter sauce becomes infused with its bold, aromatic flavor.
Step 3: Sear the Steak Bites
Heat a large skillet over medium-high heat and add a tablespoon of olive or avocado oil. Add half of your steak cubes, being careful not to overcrowd the pan—that’s crucial for getting a perfect crust. Let them sear for about 1 to 2 minutes per side until browned and cooked to your desired doneness. Transfer the steak bites to a plate and tent with foil so they stay warm. Repeat with the remaining steak.
Step 4: Sauté the Zucchini
Using the same hot pan, add a bit more oil if needed, then toss in your zucchini. Sauté for 4 to 6 minutes, stirring occasionally until the zucchini is tender-crisp and slightly browned, adding a lovely texture contrast to the soft steak.
Step 5: Create the Garlic Butter Sauce
Push the zucchini to one side of the skillet. Add a generous pat of unsalted butter and your minced garlic to the empty space. Let the butter melt completely while stirring the garlic continuously for about 30 seconds to 1 minute, just until fragrant. This step fills your kitchen with a heavenly aroma that signals the dish is nearly ready.
Step 6: Combine and Coat Everything
Return all the steak bites to the pan with the garlic butter and zucchini. Gently toss everything together so the steak, zucchini, and succulent buttery garlic sauce mingle perfectly. Taste at this stage and adjust salt or pepper if needed to balance the flavors beautifully.
Step 7: Final Touch
Sprinkle freshly chopped parsley or chives on top before serving, adding a pop of green and a burst of freshness that lifts the dish to the next level.
How to Serve Garlic Butter Steak Bites & Zucchini – Easy Low Carb Dinner Recipe

Garnishes
Fresh herbs like parsley or chives are the perfect finishing touch—they add color and a hint of brightness to the rich dish. You can also toss in a few red pepper flakes if you love a bit of heat, or a squeeze of lemon juice to cut through the butteriness.
Side Dishes
This meal shines as a complete low carb dinner on its own, but if you want some extra sides, consider a crisp green salad dressed with lemon vinaigrette or steamed asparagus for texture and fresh tastes that complement the steak bites. Cauliflower rice is another great option that keeps the carb count low while adding a comforting element.
Creative Ways to Present
Serve this dish family-style on a large platter so everyone can help themselves—it creates a warm, inviting atmosphere. You can also plate the steak bites and zucchini over creamy mashed cauliflower or alongside a colorful medley of roasted vegetables for an impressive dinner presentation.
Make Ahead and Storage
Storing Leftovers
You can store any leftover Garlic Butter Steak Bites & Zucchini – Easy Low Carb Dinner Recipe in an airtight container in the refrigerator for up to 3 days. Make sure the steak is fully cooled before storing to maintain its texture and flavor.
Freezing
This recipe freezes well. Portion the leftovers into freezer-safe containers and freeze for up to 2 months. For best results, avoid freezing the zucchini separately as it may become mushy; freezing the whole dish maintains a better texture upon reheating.
Reheating
Reheat gently in a skillet over low-medium heat until warmed through, adding a small dab of butter or oil to refresh the sauce and prevent the steak from drying out. Avoid microwaving if possible, to keep the steak tender and the zucchini crisp.
