Rainbow trout is one of my go-to recipes for weeknights. I can have it on the table from start to finish – with sides – in about 20-30 minutes. Clean up is also easy. Wrap up the tin foil or parchment the trout laid on, toss it in the garbage and put the pan back in the cupboard.
And how does it taste? Good! The sweetness and depth of the maple and balsamic flavors work really well together.
Tailor To Your Taste
- Use lime instead of lemon and add some lime or lemon zest when serving.
- Substitute the maple syrup with honey.
- Vary the heat with as much sriracha (or chili flakes) as you like.
Tips for Rainbow Trout
- The only tricks to this recipe are to buy fresh trout fillets and figure out portion size.
- My husband eats a lot, so I buy 1 1/4 to 1 1/2 pounds for the two of us.
- For “normal” eaters, 1 1/2 pounds should serve 3 people (figure 1/2 pound or 8 ounces per person). Of course portion size will also depend how substantial your side dishes are.
- A question I get a lot is how long to cook the trout. The general rule of thumb for fish is 10 minutes per inch of thickness. Start checking a minute or two earlier Peek in the center. If the flesh is just turning opaque, it’s done. It should be moist and warm pink, not dry, pale and flaky.
- To make a complete meal in one pan, roast the trout in the same pan with bok choy and broccoli (or other quick roasting vegetables. Here’s our Roasted Bok Choy and Broccoli recipe that will work perfectly. Just use an oven temperature to 425F and roast for 8-10 minutes or just until the rainbow trout is opaque.
Other great sides for the maple balsamic rainbow trout are Vegetarian Sweet Potato Hash, Parmesan Roasted Cauliflower, Grilled Corn Salad (which you can make with frozen niblets) or Roasted Veggies on Spiced Rice.
Maple Balsamic Rainbow Trout
- 1.5 lb rainbow trout fillets (2 large or 3-4 smaller)
- salt and pepper
- 2 green onions, finely chopped
- 2 tbsp chopped fresh parsley for garnish (optional)
Maple Balsamic Sauce/Glaze
- 1 1/2 tbsp good balsamic vinegar
- 1 1/2 tbsp maple syrup
- 1 1/2 tbsp fresh lemon juice
- 1/2 tsp sriracha or more (optional)
- 2 tsp olive oil
- 1 tsp cornstarch (optional)
- Preheat oven to 400F.
- MAKE SAUCE/GLAZE: Whisk together all ingredients in a small glass measuring cup or bowl. If using cornstarch to thicken the glaze, microwave sauce for 45-60 seconds to thicken.
- PREPARE TROUT: Line a pan, large enough to fit the trout, with tin foil and spray it with oil. Generously sprinkle trout with salt and pepper. Sprinkle chopped green onions over fish. Drizzle on HALF the sauce/glaze, reserving the rest for serving.
- ROAST TROUT: Roast trout for 8-11 minutes depending on the thickness of the fish. Remove from oven and cut into portions. Slip a spatula between the bottom of the fish and the skin if you want to slip off the skin. Plate the fish with any side dishes you choose. Drizzle on the remaining sauce and garnish with chopped parsley if desired.
