This grilled steak bowl combines tender, juicy steak with charred zucchini and hearty grains, all tied together with a creamy, tangy sauce. Perfect for weeknight dinners or meal prep, this versatile dish delivers restaurant-quality flavors with minimal effort.
I created this recipe when looking for ways to use summer zucchini from my garden. My family initially complained about "another zucchini dish," but they now request these bowls regularly, especially during grilling season.
Ingredients
- Sirloin or ribeye steak choose well-marbled cuts for maximum flavor and tenderness
- Zucchini look for firm, medium-sized ones with shiny skin for best texture and flavor
- Quinoa or substitute rice or farro depending on your preference
- Olive oil use a good quality oil that can withstand high heat
- Spices garlic powder and smoked paprika create a simple but flavorful crust
- Sour cream or Greek yogurt Greek yogurt offers a tangier, higher-protein alternative
- Dijon mustard adds depth and complexity to the sauce
- Fresh herbs parsley or chives bring brightness and color to the finished dish
Step-by-Step Instructions
- Prepare the Steak
- Bringing steak to room temperature ensures even cooking. Pat completely dry with paper towels to promote better searing. The spice rub is simple but effective. Apply generously and press into the meat to adhere.
- Grill the Vegetables
- Zucchini cooks quickly so maintain a watchful eye. You want nice char marks while keeping the interior tender but not mushy. The slight caramelization brings out natural sweetness in the zucchini.
- Cook the Perfect Steak
- The high heat creates a delicious crust while keeping the interior juicy. For medium rare, look for an internal temperature of 135°F. The resting period is crucial as it allows juices to redistribute throughout the meat.
- Prepare the Sauce
- Whisk ingredients vigorously to ensure a smooth consistency. The combination of creamy base with spicy Dijon creates a perfect counterpoint to the charred meat and vegetables.
- Assembly
- Slice steak thinly against the grain for maximum tenderness. Layer components strategically with grains on bottom to soak up juices, vegetables next, then meat, and finally the sauce drizzled over everything.

The smoked paprika is my secret weapon in this recipe. I discovered its transformative power years ago when a Spanish friend brought me some from her hometown. Even a small amount adds incredible depth to both the steak rub and the sauce.
Make-Ahead Options
This dish excels as a meal prep option. Cook all components and store separately in airtight containers. The steak and zucchini will keep for 3-4 days in the refrigerator. The sauce actually improves after a day as flavors meld together. When ready to eat, you can enjoy the components cold or gently reheat the steak and vegetables in a skillet with a splash of water to prevent drying out.
Vegetarian Adaptation
For a plant-based version, replace the steak with thick portobello mushroom caps or extra-firm tofu. Marinate either option in the same spice mixture plus a tablespoon of soy sauce or balsamic vinegar for 30 minutes before grilling. The mushrooms particularly develop a meaty texture and umami flavor that pairs beautifully with the creamy sauce and grilled vegetables.
Seasonal Variations
While zucchini shines in summer, this bowl concept works year-round. In spring, try asparagus and sugar snap peas. Summer allows for bell peppers, eggplant, or corn. Fall brings opportunities for butternut squash or brussels sprouts. Winter calls for hearty roasted root vegetables like carrots, parsnips, or sweet potatoes. Adjust cooking methods and times accordingly while keeping the core concept intact.
Recipe FAQs
- → What's the best way to slice steak for this bowl?
Always slice steak against the grain (perpendicular to the muscle fibers) to ensure maximum tenderness. For this bowl, thin slices about 1/4-inch thick work best for easy eating and proper distribution of flavors.
- → Can I substitute the protein in this dish?
Absolutely! While sirloin or ribeye steak creates a rich flavor profile, you can substitute with chicken breasts, salmon fillets, or even portobello mushrooms for a vegetarian option. Adjust grilling times accordingly.
- → What other vegetables work well in this bowl?
Bell peppers, asparagus, eggplant, and corn all grill beautifully and complement the flavors in this dish. Choose what's in season or add a variety for more color and nutrients.
- → How can I make this bowl dairy-free?
For a dairy-free version, replace the sour cream or Greek yogurt with dairy-free yogurt alternatives or a creamy avocado sauce. Simply blend ripe avocado with a bit of olive oil, lemon juice, garlic, and herbs.
- → Can I prepare components of this bowl ahead of time?
Yes! Cook the quinoa and prepare the sauce up to 3 days ahead. The zucchini can be grilled a day in advance. For best results, grill the steak fresh before serving, but leftover steak works well too - just don't reheat it to avoid overcooking.
- → What's the best way to achieve perfect grill marks?
Start with a very hot grill and don't move the meat or vegetables for the first few minutes. Place steak at a 45-degree angle to the grill grates, then rotate 90 degrees halfway through cooking on each side for a crosshatch pattern.
