Update a BLT with omega-3-rich Canadian rainbow trout. The combination of cornmeal-crusted trout, crispy bacon, fresh lettuce, juicy tomato and a creamy lemon-dill sauce takes this classic into new dinner-worthy territory.

The perfect weeknight meal

This one-pan meal is quick and easy to prepare. The bacon and rainbow trout are both cooked in the oven for a short time and the sauce is simple to mix together while the fish is cooking. Pair with a green salad, coleslaw or some cut up veggies and hummus and your family will be fueled up in no time.

Ready to get your kids into the kitchen?

Research tells us that the more kids help with a meal, the more likely they are to enjoy it. This is a great meal to have your child help with. They can help toss the trout in cornmeal, mix the sauce ingredients together and then assemble their whole sandwich.

No trout available?

No problem. You can also use Canadian salmon, haddock, white fish, hake or ling cod for the same delicious sandwich. And don’t worry, you can still call it a BLTT—we won’t tell.
