This is one of our favorite salmon recipes, and works with steelhead too.
The first thing you will need is two to three pounds of boneless, skinless fillets; we like these cut in strips about 6 to 8 inches long (so they will fit in a baking pan). Your fillets should be no more than an inch or so thick.
Mix the following ingredients:
4 to 5 cups sour cream
One medium size diced onion
1-1/2 tablespoon white vinegar
¾ teaspoon celery salt
1/2 teaspoon cayenne pepper
Mix ingredients, pour into baking pan and immerse fish into the mix. To add color, sprinkle before placing in oven with paprika spice. Bake at 350 degrees for 30 to 35 minutes. If more fish, you can double or triple layer but will likely need more ingredients and cooking time.
We like this dish served over rice!
