Ingredient Note List

Sirloin Steak: I always choose sirloin that’s about 1 inch thick because it cooks evenly and stays tender when broiled, giving you that perfect balance of seared exterior and juicy interior.

Fresh Broccoli: Make sure to cut your broccoli into similar-sized florets so they roast evenly alongside the steak without becoming mushy or undercooked.

Asparagus Spears: Look for asparagus that’s firm with tight tips – these hold their shape beautifully under the broiler and add a lovely bright green color to your keto sheet pan.

Butter: I prefer using real butter at room temperature because it mixes easily with the herbs and creates that rich, creamy base for the caper butter.

Fresh Rosemary: Fresh rosemary makes all the difference in this recipe – it releases amazing aromatics when heated and pairs perfectly with the beef’s savory flavors.

Capers: These little bursts of briny flavor brighten up the rich butter and steak combination, adding that gourmet restaurant touch to your weeknight dinner.

Garlic: Mincing the garlic into a paste helps it distribute evenly through the butter, ensuring every bite of steak gets that wonderful garlicky flavor.

Olive Oil: Use just enough olive oil to coat the vegetables lightly – this helps them caramelize beautifully without adding unnecessary carbs to your keto meal.

How to Cook Keto Steak and Veggies Sheet Pan

Step 1. I always start by setting my oven to broil and placing the empty sheet pan inside to heat up – this trick gives the steak a restaurant-quality sear from the moment it hits the pan.

Step 2. While the pan heats, I mash together the softened butter, chopped rosemary, capers, and garlic paste in a small bowl until well combined.

Step 3. My grandmother always said to shape compound butter into a log using plastic wrap, and she was right – it makes slicing so much easier once it’s chilled.

Step 4. I pat the steaks completely dry with paper towels and season both sides generously with salt and pepper – moisture is the enemy of a good sear.

Step 5. In my experience, tossing the vegetables with just enough olive oil to coat them lightly helps them develop those beautiful caramelized edges.

Step 6. I carefully remove the hot sheet pan from the oven using thick oven mitts, then drizzle a bit of olive oil where the steaks will go.

Step 7. I place the seasoned steaks toward the center of the hot pan and arrange the oiled vegetables around the edges – you’ll hear that satisfying sizzle immediately.

Step 8. After 5 minutes under the broiler, I flip the steaks and return the pan to broil for another 5 minutes or until they reach your preferred doneness.

Step 9. I top each steak with a slice of that chilled rosemary caper butter right before serving – it melts beautifully over the hot meat.

How to Store & Reheat

I usually store any leftover keto steak and veggies in an airtight container in the refrigerator, where they stay fresh for up to 3 days. The vegetables actually develop even more flavor overnight, though the steak is best enjoyed fresh.

For freezing, I don’t recommend it for this particular dish since steak can become tough when frozen and reheated, and the vegetables lose their appealing texture.

For best results, I like to reheat leftovers gently in a 300°F oven for about 10 minutes, just until warmed through. You can also use the microwave on 50% power for 1-2 minutes, but be careful not to overcook the steak.

What to Serve with Keto Steak and Veggies Sheet Pan

Cauliflower Rice: The mild, fluffy texture of cauliflower rice soaks up those delicious pan juices beautifully while keeping your meal perfectly keto-friendly.

Zucchini Noodles: These light, fresh noodles provide a wonderful contrast to the rich, savory flavors of the steak and herb butter combination.

Simple Arugula Salad: The peppery bite of arugula with a light vinaigrette cuts through the richness of the meal and adds a fresh, crisp element.

Roasted Brussels Sprouts: In my kitchen, I often add Brussels sprouts right to the sheet pan, or I serve them alongside Baked Salmon and Asparagus for a double sheet-pan dinner night for an extra serving of vegetables that caramelize alongside everything else.

Avocado Slices: Creamy avocado provides healthy fats and a cooling contrast to the warm, seasoned steak and vegetables.

Keto Garlic Bread: Made with almond flour, this satisfying side helps round out the meal while staying within your carb limits.
