12 Best Tuna Recipes for Bulking (High Protein, Easy Prep)

Tuna is one of the most underrated bulking foods out there. It's cheap, packed with protein, requires almost zero cooking skill, and you can turn it into a meal in under 10 minutes.

A single can of tuna gives you 30-40g of protein for about a dollar. That's better bang for your buck than most protein powders. And unlike chicken breast, you don't need a grill, a pan, or even a functioning kitchen — just a can opener.

But here's the thing most skinny guys get wrong: they eat tuna the same boring way every time. Plain tuna on rice. Tuna out of the can. Repeat until you never want to see tuna again.

That's a waste. Tuna is incredibly versatile, and with the right recipes, it becomes one of the easiest ways to hit your protein and calorie targets without spending hours in the kitchen.

Here are 12 tuna recipes that actually taste good, hit serious macros, and take minimal effort.

Canned vs Fresh Tuna: What to Buy

Before we get into recipes, let's clear up what kind of tuna to use.

Canned Tuna (The Budget King)

For everyday bulking, canned chunk light tuna is your best friend. It's the cheapest option, lower in mercury than albacore, and you can eat it more frequently.

Fresh Tuna Steaks (The Premium Option)

Fresh tuna steaks are great for variety, but they're more expensive and require actual cooking. Save these for 1-2 meals per week when you want something that feels like a real dinner.

A 6 oz tuna steak gives you roughly 40g protein and 200 calories.

Quick Note on Mercury

You've probably heard that tuna has mercury. Here's what you actually need to know:

• Chunk light tuna (skipjack) is low in mercury — you can safely eat it 4-5 times per week
• Albacore (white) tuna is higher in mercury — limit to 2-3 times per week
• Fresh tuna steaks — same as albacore, 2-3 times per week max

If you're eating tuna daily, stick to chunk light. Mix in other protein sources like chicken, eggs, and ground beef throughout the week to keep things balanced.

How to Fit Tuna Into Your Bulking Plan

Here's a sample day using tuna as your primary protein source:

That's a solid bulking day for a 150-170 lb guy. If you need more, check our 3500-calorie meal plan for a complete framework.

Common Mistakes With Tuna

1. Only buying tuna in water. If you're bulking, the oil adds easy calories. Stop draining away free energy.

2. Eating it plain. Tuna out of the can gets old fast. Season it, mix it with sauces, combine it with carb sources. Sustainability matters more than perfection.

3. Not tracking the oil. If you use tuna in oil, count those calories. The oil alone adds 80-100 calories per can.

4. Ignoring mercury guidelines. Stick to chunk light for daily use. Save albacore and fresh steaks for 2-3 times per week.

5. Forgetting to pair with carbs. Tuna is almost pure protein. You need rice, pasta, bread, or potatoes alongside it to hit your calorie targets.
