Tuna 101: What You Need to Know About Tuna Cubes and Tuna Block

When we think of tuna, we often picture it in a can or as sushi—but did you know that the way your tuna is cut and prepared can completely change how it cooks and tastes?
Today, let’s dive into something every home cook and seafood lover should learn: the difference between Tuna Cubes and Tuna Blocks, and how to make the most of each.

Know Your Cuts

Tuna Cubes are small, bite-sized pieces of tuna loin—usually about 1 inch thick. They’re great for quick-cooking methods like stir-frying, sautéing, or grilling. Because of their size, they absorb marinades well and cook evenly.

Tuna Blocks, on the other hand, are thicker rectangular cuts that give you flexibility. You can slice them into sashimi, sear them for steaks, or cube them yourself. They’re perfect if you want more control over how your dish turns out.

Think of Tuna Cubes as “ready-to-cook convenience,” while Tuna Blocks are “chef’s choice flexibility.”

Cooking Techniques Matter

Tuna is a delicate fish—it’s easy to overcook. Here’s what you can learn to bring out its best flavor:

For Tuna Cubes: Cook on high heat for a short time (1–2 minutes per side). Great for tuna salpicao or tuna sisig.

For Tuna Blocks: Try searing the outside while keeping the center pink—like a medium-rare steak. You’ll keep it juicy and flavorful.

Tuna tastes best when it’s slightly pink in the center. Overcooking makes it dry and chewy.

Nutrition You Should Know

Tuna isn’t just delicious—it’s also one of the healthiest proteins you can eat.
It’s packed with:

Omega-3 fatty acids for heart health

High-quality protein for muscle repair

Vitamins B12 and D for energy and immunity

So, whether you’re cooking Tuna Cubes for a quick dinner or Tuna Blocks for a weekend meal, you’re fueling your body with something truly good for you.

Sustainability Counts

Choosing tuna from trusted sources—like Fat Butcher PH—means you’re supporting responsible fishing practices. That’s a small step that helps protect marine life and ensures that future generations can still enjoy fresh, healthy seafood.

Learning about tuna cuts might sound simple, but it can change the way you cook.

Use Tuna Cubes when you want quick, flavorful meals.

Use Tuna Blocks when you want to be creative in the kitchen.

Always cook with care and respect for the ingredient.

With every dish, you’re not just feeding your family—you’re learning, creating, and appreciating good food.
