This is one of my favorite weeknight dinners because it comes together in just 40 minutes total, and honestly, it feels way fancier than the effort requires. Tuna steaks are absolutely packed with omega 3 fatty acids that are wonderful for your heart and brain, plus they cook so quickly that you won't be stuck in the kitchen for long. The pea and lemon butter sauce is bright and silky, transforming simple ingredients into something really special. Best of all, you probably have most of these things on hand already, so it's budget friendly too. Whenever I make this, my family thinks I've done something elaborate, but really I'm just roasting some beautiful fish and stirring together a quick pan sauce. Give it a try and see what I mean.

Instructions
- 1
Pat tuna steaks dry with paper towels and season generously on both sides with sea salt and black pepper about 10 minutes before cooking.
Tip: Bringing tuna to room temperature ensures even cooking throughout the steak.
- 2
Heat olive oil in a large cast iron skillet over medium-high heat until shimmering, then sear tuna steaks for 2-3 minutes per side for medium-rare doneness. Transfer to a resting plate.
Tip: Avoid moving the tuna while searing to develop a golden crust.
- 3
In the same skillet, melt 2 tablespoons of butter over medium heat and add minced garlic and diced shallot, stirring constantly for 1-2 minutes until fragrant.
Tip: Keep heat at medium to prevent burning the garlic.
- 4
Pour white wine into the skillet and let it reduce by half, about 2 minutes, scraping up any browned bits from the pan.
Tip: These browned bits add tremendous flavor to your sauce.
- 5
Add frozen peas directly to the skillet and stir gently, cooking for 3-4 minutes until heated through and tender-crisp.
Tip: No need to thaw peas; they cook perfectly from frozen.
- 6
Remove from heat and stir in remaining 2 tablespoons of butter, fresh lemon juice, lemon zest, and fresh thyme sprigs until the butter melts into a silky sauce.
Tip: Adding butter off-heat creates a smoother emulsion without breaking.
- 7
Taste the pea mixture and adjust seasoning with additional salt and pepper as needed.
Tip: The sauce should be bright and balanced between buttery and acidic.
- 8
Divide roasted peas with sauce among four plates and top each with a tuna steak. Serve immediately while tuna is still warm.
Tip: Serve right away for best presentation and temperature contrast.
