How to Make Keto Mediterranean Creamy Tomato Tuna with Sautéed Broccoli and Cauliflower

You've got this. Here's everything you need and exactly how to pull it together.

What You'll Need

For the sautéed vegetables:

• 2 cups broccoli florets
• 2 cups cauliflower florets
• 2 tbsp olive oil
• Salt, pepper, and a pinch of red pepper flakes

For the creamy tomato tuna sauce:

• 2 cans (5 oz each) tuna in olive oil, drained
• 1 cup crushed tomatoes
• ⅓ cup heavy cream
• 3 garlic cloves, minced
• 2 tbsp capers
• ¼ cup Kalamata olives, halved
• 1 tsp dried oregano
• Fresh basil to finish

Step-by-Step Instructions

Step 1: Sauté the vegetables. Heat olive oil in a large skillet over medium-high heat. Add broccoli and cauliflower florets in a single layer. Let them sit — no stirring — for 2–3 minutes to get that golden, caramelized edge. Season with salt, pepper, and red pepper flakes. Toss and cook another 3–4 minutes until tender-crisp. Set aside.

Step 2: Build the sauce. In the same skillet, reduce heat to medium. Add a splash more olive oil if needed, then sauté garlic for 60 seconds until fragrant. Add crushed tomatoes, oregano, capers, and olives. Stir and let it simmer for 5 minutes.

Step 3: Add cream and tuna. Pour in the heavy cream and stir to combine. Fold in the drained tuna gently — you want chunks, not mush. Simmer for another 3–4 minutes until the sauce thickens slightly.

Step 4: Bring it together. Return the sautéed broccoli and cauliflower to the pan. Toss everything together so the veggies get coated in that gorgeous sauce. Finish with fresh basil and a drizzle of good olive oil.

Pro Tips for the Best Results

• Don't overcrowd the pan when sautéing — that's how you get steam instead of color. Work in batches if needed.
• Use tuna in olive oil, not water. The flavor difference is real, and it keeps the dish from feeling dry.
• Taste before salting — capers and olives bring their own saltiness, so go easy at first.
• Do yourself a favor and squeeze a little lemon over the top right before serving. It brightens everything up.
