Roasted Tomatillo Salmon from Casa Marcela

The smell of roasting tomatillos instantly transports me back to my grandmother’s kitchen. As a child, I’d watch her meticulously peel away the papery husks, revealing the vibrant green orbs within. She’d tell me stories of how the Aztecs revered tomatillos, their tartness a signature of our culture. While she most often used them in her famous salsas, she sometimes roasted them to mellow their intensity, and I remember a particular meal when, instead of chicken, she paired them with flaky salmon. That simple combination of bright acidity and rich, savory fish became an instant favorite, a taste of home that I cherish to this day. This recipe, reminiscent of her style, allows me to recreate that cherished memory in my own kitchen, and now I share it with you.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 35 minutes
• Total Time: 50 minutes
• Servings: 4
• Dietary Type: Gluten-Free

Ingredients

• 1 1/2 lbs small tomatillos, husked, rinsed, and sliced into 1/2-inch rounds
• 2 cups thinly sliced red onions
• 2 tablespoons extra-virgin olive oil
• Salt & freshly ground black pepper to taste
• 1 (2 lb) Atlantic salmon fillet
• 1 lemon, cut into 6 thin slices
• 1 tablespoon chopped fresh chives
• 1 tablespoon chopped fresh cilantro
• White Rice With Basil and Corn for serving with salmon (optional, see variations section)

Equipment Needed

• Baking sheet
• Parchment paper
• Large bowl

Instructions

1. Preheat your oven to 375 degrees F (190 degrees C). Line a baking sheet with parchment paper. This will prevent sticking and make cleanup a breeze.

2. In a large bowl, combine the sliced tomatillos and thinly sliced red onion. Drizzle with extra-virgin olive oil, then season generously with salt and freshly ground black pepper. Toss everything together thoroughly to ensure the vegetables are evenly coated with oil and seasoning.

3. Spread the tomatillo and red onion mixture onto the prepared baking sheet in an even layer.

4. Place the Atlantic salmon fillet directly on top of the tomatillo and onion mixture.

5. Season the salmon fillet with salt and pepper to taste. Don’t be shy with the seasoning; it will enhance the flavor of the fish.

6. Arrange the lemon slices evenly across the top of the salmon fillet. Then, sprinkle the chopped fresh chives and chopped fresh cilantro over the lemon slices and the fish.

7. Roast the salmon and tomatillo mixture in the preheated oven for 20 minutes for rare salmon. If you prefer your salmon cooked more thoroughly, you may need to add a few minutes to the cooking time.

8. Carefully transfer the salmon fillet to a serving platter.

9. Return the tomatillo and onion mixture to the oven and continue to roast until the vegetables are softened and caramelized, about 15 minutes. Keep a close eye on them to prevent burning. The natural sugars in the vegetables will start to caramelize, creating a delicious, slightly sweet flavor.

10. To serve, arrange the roasted tomatillos and onions alongside the salmon fillet on the serving platter. Serve immediately with White Rice With Basil and Corn, if desired.

Expert Tips & Tricks

• Don’t overcrowd the pan: Ensure the tomatillos and onions are spread in a single layer. Overcrowding steams the vegetables instead of roasting them, preventing proper caramelization. Use a larger baking sheet if necessary.
• Salmon Doneness: The best way to check if your salmon is done is to gently flake it with a fork. If it separates easily and the flesh is opaque, it’s ready. Remember, slightly undercooked is preferable to overcooked salmon, which can be dry.
• Tomatillo Selection: Opt for smaller tomatillos, if available. Their flavor tends to be sweeter and less acidic than larger ones.
• Lemon Zest Boost: Add a teaspoon of lemon zest to the salmon before roasting to amplify the citrus notes.
• Spice it up: A pinch of red pepper flakes added to the tomatillo mixture will add a subtle kick of heat to the dish.

Serving & Storage Suggestions

Serve the Roasted Tomatillo Salmon immediately for the best flavor and texture. The bright, tangy tomatillos and sweet onions perfectly complement the rich salmon.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the salmon and vegetables in a low oven (275 degrees F or 135 degrees C) or in a skillet over medium-low heat until heated through. Microwaving is not recommended, as it can dry out the salmon.

Variations & Substitutions

• Spice Level: For a spicier dish, add a finely chopped jalapeño pepper to the tomatillo mixture.
• Other Fish Options: If you can’t find Atlantic salmon, you can substitute with other types of salmon, such as Coho or Sockeye. Cod or halibut would also work well.
• Herb Variations: Experiment with other fresh herbs like oregano, thyme, or rosemary in place of, or in addition to, the chives and cilantro.
• White Rice with Basil and Corn: While the original recipe suggests serving this with white rice with basil and corn, you could easily substitute with quinoa, couscous, or roasted vegetables for a low-carb option.
• Tomatillo Salsa Verde: If you don’t have fresh tomatillos, you could use a store-bought or homemade tomatillo salsa verde. Roast the onions separately and then toss with the salsa after roasting.
