Ingredients List

Main Ingredients:

  • 1.5 lbs Sirloin Steak or Ribeye: Cut into bite-sized 1-inch cubes.
  • 3 Medium Zucchini: Spiralized into fresh zucchini noodles (zoodles).
  • 3 tbsp Unsalted Butter: Divided for searing steak and cooking garlic zoodles.
  • 1 tbsp Extra Virgin Olive Oil: Helps achieve a high-heat sear without burning the butter.
  • 4 Cloves Garlic: Finely minced for maximum flavor.
  • 1 tsp Italian Seasoning
  • 1/2 tsp Smoked Paprika
  • Salt & Freshly Ground Black Pepper: To taste.

Optional Toppings & Variations:

  • 1/4 cup Grated Parmesan Cheese: For an extra creamy, savory finish.
  • Fresh Lemon Juice: A squeeze of lemon brightens up the heavy butter sauce.
  • Red Pepper Flakes: Add 1/2 tsp for an extra kick of heat.
  • Mushroom Twist: Sauté sliced cremini mushrooms alongside the garlic for added texture.

Step-by-Step Instructions

  1. Prep & Season the Steak: Pat the steak cubes completely dry with paper towels (dry meat sears better). Season generously on all sides with salt, pepper, Italian seasoning, and smoked paprika.
  2. Sear the Steak Bites: Heat 1 tablespoon of butter and 1 tablespoon of olive oil in a heavy cast-iron skillet over high heat. Add the steak in a single layer without overcrowding. Cook undisturbed for 2-3 minutes to build a rich brown crust, then flip and cook for another 1-2 minutes. Remove steak from skillet and transfer to a plate.
  3. Cook Garlic & Zucchini Noodles: Turn heat down to medium. Add the remaining 2 tablespoons of butter and minced garlic to the same pan. Sauté for 1 minute until fragrant. Toss in the spiralized zucchini noodles and saute for 2 minutes—do not overcook to avoid excess water!
  4. Combine & Serve: Add the cooked steak bites and accumulated juices back into the skillet with the noodles. Toss everything together for 30 seconds. Garnish with chopped fresh parsley and grated Parmesan cheese, then serve immediately.

Storage & Meal Prep Tips

  • How to Store: Store leftovers in an airtight glass container in the refrigerator for up to 3 to 4 days.
  • Pro-Tip for Meal Prep: Keep cooked steak bites and uncooked raw zoodles separate when packing lunches. Combine and heat together right before eating so the zucchini stays crisp!
  • Reheating: Reheat in a skillet over low-medium heat for 2-3 minutes. Avoid microwaving on high heat as steak can turn tough and rubbery.

Frequently Asked Questions (FAQs)

Q: Which cut of beef is best for steak bites?

A: Top sirloin, ribeye, or tenderloin (filet mignon) are the best choices because they stay remarkably tender when cooked quickly over high heat.

Q: How do I stop my zucchini noodles from becoming watery?

A: Do not salt your zoodles before cooking, and cook them for no more than 2 minutes in the pan. Zucchini releases moisture rapidly as it cooks!

Q: Can I freeze this meal?

A: Steak bites freeze well for up to 2 months, but zucchini noodles do not freeze well as they lose structural integrity upon thawing.
