How to Make Buttered Reineta?
Use fresh or properly thawed reineta fillets. Pat them completely dry with paper towels before they go into the pan — surface moisture prevents browning and causes the fish to steam instead of sauté. The combination of butter and olive oil gives a richer flavor than either fat alone while keeping the butter from burning.

Homemade Buttered Reineta Recipe
Prep Time: 10 minutes
Cook Time: 20 minutes
Servings: 4
Ingredients
- 4 reineta fillets
- 2 onions, finely diced
- 2 garlic cloves, crushed
- 2 tablespoons butter
- Extra virgin olive oil
- Fresh parsley
- Merkén (smoked chili pepper)
- Salt
- Pepper
Instructions
- Wash and clean the reineta fillets, remove excess moisture with paper towels, and set aside.
- In a large pan, add a splash of olive oil, the diced onion, crushed garlic, and butter. Sauté over low heat for about 10 minutes until the onion is soft and translucent.
- Season the reineta fillets with salt, pepper, and optionally a pinch of merkén on both sides. Carefully add them to the pan. Cover and cook over low heat for about 3 minutes, then flip carefully and cook for an additional 1 to 2 minutes until the flesh is opaque throughout.
- Serve immediately, garnished with fresh parsley, accompanied by mashed potatoes or crispy fries.
Additional Tips
Pat the fillets completely dry before cooking
Surface moisture is the main reason fish fillets fail to brown properly. After washing the reineta, press each fillet firmly with paper towels on both sides. Dry fillets sear cleanly in the pan and develop a slightly golden exterior; wet fillets steam and turn grey. This single step makes the biggest difference in the finished result.
Use low heat to let the butter work without burning
Reineta fillets are thin and cook quickly — low to medium-low heat is all they need. High heat burns the butter before the fish is cooked through and toughens the delicate flesh. If the butter starts browning too quickly, add a small splash of olive oil to raise the smoke point and lower the temperature momentarily.
Start skin-side down for a crispier result
If your fillets have the skin on, place them skin-side down first and press gently with a spatula for the first 30 seconds to prevent curling. Cook until the skin is visibly crisp and golden before flipping — this typically takes 3 to 4 minutes. The skin acts as a natural barrier that keeps the flesh moist during cooking.
| Ingredient | Substitution and result |
|---|---|
| Reineta fillets | Sole, flounder, or tilapia — same thin white fish profile; same cooking time |
| Butter | Olive oil only — lighter result; loses the characteristic richness of the butter base |
| Merkén | Smoked paprika + a pinch of cayenne — closest substitute outside Chile |
| Fresh parsley | Fresh cilantro — more assertive flavor; commonly used in other Chilean fish preparations |
| Onion | Shallots — milder and sweeter; won’t overpower the delicate flavor of the reineta |
Frequently Asked Questions (FAQs)
1. What is reineta fish?
Reineta (Brama australis), known in English as pomfret or warehou, is a deep-water white fish native to the South Pacific. In Chile, it is one of the most widely available and affordable fish, sold in markets from Arica to Punta Arenas. Its mild, slightly sweet flavor and lean flesh make it a weekday staple in Chilean home cooking.
2. Can I cook reineta on a grill instead of a pan?
Yes. Make sure the grill surface is hot and lightly oiled before placing the fillets to prevent sticking. Start skin-side down over medium-high heat for 3 to 4 minutes until the skin is crispy, then flip and cook for 1 to 2 more minutes. Baste with the butter and onion mixture from the pan during grilling for the same flavor profile.
3. How do I prevent the fillets from sticking to the pan?
Three factors prevent sticking: a well-heated pan before the fish goes in, dry fillets (moisture causes sticking), and enough fat in the pan. Do not move the fillet immediately after placing it — let it cook undisturbed for the first 2 to 3 minutes until it releases naturally from the surface.
4. What side dishes go well with buttered reineta?
Mashed potatoes and crispy fries are the most traditional pairings. Chilean salad (tomato, onion, cilantro) also works well. For a lighter meal, steamed rice or a simple green salad with lemon dressing complements the richness of the butter without overwhelming the delicate fish.
What Is Reineta?
Reineta (Brama australis) is a deep-water fish of the South Pacific, also known as pomfret or warehou in English-speaking markets. In Chile, it is one of the most consumed and affordable white fish, available year-round in fish markets and supermarkets across the country. Reineta has a mild, slightly sweet flavor with lean, firm flesh that flakes cleanly — characteristics that make it suitable for pan-frying, grilling, baking, and soups. It is particularly popular in central and southern Chile, where it is caught along the Pacific coast.
History of Buttered Fish in Chilean Cuisine
The “a la mantequilla” (buttered) preparation is a French-influenced technique that became common in Chilean home cooking during the 19th century, when European immigrants — particularly French and Spanish — introduced butter-based cooking methods to Chilean kitchens. Before refrigeration, fresh fish was a perishable ingredient consumed close to the coast, but as transportation improved in the 20th century, reineta and other Pacific fish became accessible across the country. The buttered preparation remains one of the simplest and most widespread ways to cook fish in Chilean households.
Did you know?
Reineta is one of the leanest and most affordable white fish available in Chile, with fewer than 2 g of fat per 100 g of raw fillet. Despite its low calorie content, it provides a complete protein profile with all essential amino acids, making it a nutritionally efficient option for everyday meals.
