Nutritious ingredients: Rich in vitamins, minerals, and healthy protein.

Delicious and layered flavors: The salsa verde brings boldness, freshness, and just the right amount of spice.

What Makes Salsa Verde Special?

Salsa verde (“green sauce”) is a flavorful condiment found in many global cuisines. In this recipe, the focus is on the Mexican variety, built from tomatillos, cilantro, onion, garlic, and jalapeño. The sauce is blended and simmered to bring out its tart, herbal, and slightly smoky flavors—a perfect poaching liquid for mild fish like cod.

Cilantro: Love It or Loathe It?

Cilantro is a divisive herb. According to nutrition experts, some people perceive it as citrusy and fresh, while others detect a strong soapy aftertaste due to genetic factors. Cilantro is not only flavorful but also a good source of folate and vitamin C, making it a nutritious addition to this recipe.

Ingredients

This recipe centers on easily accessible, wholesome staples that contribute to both its flavor and nutrition:

2 cups cilantro leaves and stems, divided
1 large white onion, quartered
1 lb. tomatillos, husked and roughly chopped
2 cloves garlic
1 jalapeño, seeded and roughly chopped
2 Tbsp plus 1 tsp fresh lime juice, divided
Kosher salt
4 cod fillets (6 oz. each)
1 tsp olive oil
5 radishes, thinly sliced

How to Make Salsa Verde–Poached Fish

Prepare the Salsa Verde:
Reserve 1/4 cup of the cilantro for serving. Place the rest into a blender. Roughly chop three-quarters of the onion and add it, along with the tomatillos, garlic, jalapeño, and 2 tablespoons lime juice. Blend until mostly smooth, seasoning with a generous pinch of kosher salt. This vibrant sauce forms both the poaching liquid and the primary flavor base.

Poach the Fish:
Using a deep skillet or sauté pan over medium heat, add 1 teaspoon of olive oil. Slice the remaining onion and sauté until just translucent. Pour in the salsa verde and bring it to a simmer. Season the cod fillets with a little salt, then gently nestle them into the sauce. Spoon salsa over the fish to partially submerge and cover the fillets. Poach for about 8 to 10 minutes, or until the fish is just cooked through and flakes easily with a fork. Add the remaining 1 teaspoon lime juice in the last minute of cooking.

Expert Tips for Perfect Salsa Verde–Poached Fish

Use fresh cilantro: Both leaves and stems are fragrant and full-flavored for salsa verde.
Do not overcook: Keep the poaching liquid at a simmer, not a rolling boil, to maintain moist, tender fish.
Adjust the heat: Remove the seeds and membrane of the jalapeño for less spice. For more kick, add extra chili.
Garnish generously: Reserved cilantro and radishes add crunch and color just before serving.
Prep in advance: Make salsa verde up to 2 days ahead for faster weeknight cooking.

Recipe Variations and Serving Suggestions

Fish alternatives: Try halibut, haddock, or tilapia in place of cod, adjusting cook time based on thickness.
Add more vegetables: Simmer sliced carrots, zucchini, or leafy greens in the salsa with the fish.
Make it a bowl: Serve poached fish and salsa over brown rice or quinoa for a hearty meal.
Toppings and sides: Pair with warm tortillas, guacamole, and black beans for a fuller spread.

Understanding Poaching: Gentle Cooking for Maximum Flavor

Poaching is a gentle, moist-heat cooking method ideal for delicate ingredients like fish. By simmering cod in salsa verde—rather than baking or frying—you preserve its flaky texture and prevent it from drying out. This approach also infuses the fish with the vibrant flavors of the sauce, avoiding the need for heavy seasoning or breading.

Cilantro: The Science of Taste

It’s not just culinary lore—cilantro preference does come down, in part, to genetics. Some people have a variation in genes related to olfactory receptors, making them more likely to perceive cilantro’s so-called soapy taste. If you’re in the “cilantro-tastes-fresh” camp, you’ll love its citrus-like zing in salsa verde. If not, try substituting with a milder herb like parsley for a modified green sauce that still offers plenty of freshness without the pungency.

The Story Behind Salsa Verde

Salsa verde has deep roots in Mexican cuisine, where it’s traditionally made with tomatillos—a small, tart green fruit enveloped in a papery husk. Combined with cilantro, onion, garlic, and chilies, it delivers bright, savory notes that complement everything from tacos to grilled meats, and, of course, gently poached fish. Across Italy and Spain, variations exist using herbs, capers, and olive oil, showing the sauce’s diversity and broad appeal.

Frequently Asked Questions (FAQs)

What type of fish works best for salsa verde poaching?

Mild, flaky white fish like cod, halibut, or haddock are ideal. You can also use other firm fish like tilapia or snapper; just adjust cooking time for thickness.

Can I make the salsa verde ahead of time?

Yes—prepare the sauce up to two days in advance and refrigerate. The flavors actually deepen, making poaching even more delicious.

Troubleshooting and Common Pitfalls

Fish falls apart: Watch the cooking time carefully and use a spatula to move fish gently.
Overly sour salsa: Adjust with a pinch of sugar or a little extra olive oil for balance.

More Tips for Success

Season in layers: Salt both the sauce and the fish for maximum flavor.
Let it rest: Allow the fish to sit for a minute after poaching for easier serving.
Herb swaps: Try parsley or basil if you don’t like cilantro, or mix a variety for unique flavors.
