Why Tuna and Roasted Cauliflower Steak is Perfect for Weight Loss
Eating healthy doesn’t have to be boring—it just needs to be balanced and satisfying. This dish does just that, offering a medley of textures and flavors while helping you stick to your goals.
Here’s why it works so well:
- Low in Calories, High in Nutrients: Cauliflower is a low-calorie vegetable, with just 25 calories per cup. It’s also high in fiber, keeping you fuller for longer and supporting healthy digestion.
- Rich in Lean Protein: Tuna provides about 20 grams of protein per 3-ounce serving. Protein is essential for preserving muscle mass while losing weight.

A study published in The American Journal of Clinical Nutrition found that high-protein, low-calorie diets significantly improve weight loss and muscle preservation.
Ingredients for Tuna and Roasted Cauliflower Steak
To make this dish, you’ll need a handful of fresh, high-quality ingredients:
For the Roasted Cauliflower Steaks
- 1 large cauliflower head
- 2 tablespoons olive oil
- 1 teaspoon garlic powder
- Salt and pepper to taste
For the Seared Tuna
- 2 tuna steaks (about 6 oz each)
- 1 tablespoon olive oil
- Salt and pepper to taste
- 1 teaspoon smoked paprika (optional)
For the Lemon-Parsley Gremolata
- Zest of 1 lemon
- 2 tablespoons fresh parsley, finely chopped
- 1 garlic clove, minced
- 1 tablespoon olive oil
For the Caper Butter
- 2 tablespoons unsalted butter
- 1 tablespoon capers, drained and chopped
- 1 teaspoon lemon juice
Step-by-Step Recipe: Tuna and Roasted Cauliflower Steak
1. Prepare the Cauliflower Steaks
- Slice the Steaks: Preheat your oven to 400°F (200°C). Remove the leaves and trim the stem of the cauliflower, keeping the head intact. Slice it vertically into 1-inch-thick steaks.
- Season and Roast: Brush both sides of the cauliflower steaks with olive oil. Sprinkle with garlic powder, salt, and pepper. Arrange on a baking sheet and roast for 20 minutes, flipping halfway through. The steaks should be golden brown and tender.
2. Sear the Tuna Steaks
- Season the Tuna: Pat the tuna steaks dry with a paper towel. Rub with olive oil and season generously with salt, pepper, and smoked paprika if using.
- Sear in a Pan: Heat a skillet over medium-high heat. Sear the tuna for 1-2 minutes on each side for medium-rare, or longer if you prefer it more cooked. Set aside to rest.
3. Make the Lemon-Parsley Gremolata
Combine Ingredients: In a small bowl, mix the lemon zest, parsley, minced garlic, and olive oil. Stir until well combined.
4. Prepare the Caper Butter
- Melt and Mix: In the same skillet used for the tuna, melt the butter over low heat. Stir in the capers and lemon juice. Heat for 1-2 minutes until fragrant.
5. Plate and Serve
- Assemble the Dish: Place a roasted cauliflower steak on each plate. Top with a tuna steak. Drizzle with the caper butter and sprinkle with the lemon-parsley gremolata.
- Serve Immediately: This dish is best enjoyed fresh while the cauliflower is warm and the tuna is tender.
