Ingredients

• 12 ounces / 340g Haddock Fillets
• 1 tbsp / 14g Butter
• ½ cup / 120ml Heavy Cream
• 5 ounces / 140g Sharp Cheddar Cheese, freshly grated
• 3 tbsp / 45g Onions, finely diced
• ¼ tsp / 1.5g Garlic Salt
• ¼ tsp / 0.5g Black Pepper, freshly ground

Instructions

1. Directions
2. Set your Instant Pot to the SAUTE function. Once hot, add the butter and let it melt completely.
3. Add the finely diced onions and sauté for 2-3 minutes, stirring occasionally, until they become soft and fragrant.
4. Gently pat the haddock fillets dry and season both sides generously with garlic salt and black pepper.
5. Carefully place the seasoned fillets into the Instant Pot. Sear for 2 minutes per side to develop a light golden crust. Turn off the SAUTE function.
6. Pour the heavy cream evenly over the fish, then sprinkle the grated cheddar cheese on top.
7. Secure the lid, set the steam valve to ‘Sealing,’ and cook on HIGH PRESSURE (or MANUAL) for 5 minutes.
8. Once the cooking cycle is complete, allow the pressure to release naturally for 5 minutes before performing a quick release to vent the remaining steam.
9. Carefully open the lid, serve the cheesy haddock immediately, and enjoy every creamy bite!

Pro Tips

• For the best flavor and melt, grate your own block of sharp cheddar cheese. Pre-shredded cheeses often contain anti-caking agents that can make the sauce grainy.
• Don’t have haddock? This recipe works beautifully with other firm white fish like cod, pollock, or halibut. Adjust cook time slightly for thicker fillets.
• Serve this creamy fish over a bed of steamed asparagus, zucchini noodles, or cauliflower rice to keep it low-carb and soak up all the delicious sauce.
