How to Make Instant Pot Mediterranean-Style Fish Stew Recipe

Step 1: Season and Prepare the Fish

The first secret to flavorful fish is seasoning. If time allows, pat your fish dry and sprinkle generously with salt and pepper about 15 minutes before cooking to enhance the natural flavors and draw out moisture. This dry brining step helps keep the fish wonderfully tender once cooked. If you’re short on time, simply season them and move on; the stew will still be delicious!

Step 2: Sauté the Vegetables

Switch your Instant Pot to “Sauté” mode to warm the garlic-infused olive oil. Once hot, add the aromatic leeks, sweet carrots, crunchy celery, and red potatoes seasoned with a pinch of salt. Stir frequently for about three minutes to develop depth of flavor and soften the veggies just slightly while keeping their structure. This step builds a robust foundation for the stew.

Step 3: Deglaze the Pot

Next, cancel the sauté mode and pour in one cup of broth. Use a spoon or spatula to scrape up all those golden browned bits stuck to the pot’s bottom. These bits are pure flavor gold and give the stew complexity. Deglazing also prevents a “burn” notice during pressure cooking.

Step 4: Add Remaining Ingredients

Pour in the remaining two cups of broth and the diced tomatoes with their juice. Sprinkle in dried chives, dill, the remaining salt and pepper, then stir everything together. Each seasoning and vegetable enhances the rich Mediterranean flair you’re aiming for here.

Step 5: Add the Fish and Bay Leaf

Gently nestle the seasoned fish chunks on top of the vegetable broth—resist stirring now to keep the fish pieces intact during cooking. Toss in the bay leaf for an aromatic boost, and get ready to seal the lid.

Step 6: Pressure Cook for Perfect Results

Seal your Instant Pot and ensure the valve is set to “Sealing.” Select “Manual” or “Pressure Cook” and set the timer to 3 minutes. This short cooking time is key to avoid overcooking delicate fish while perfectly tenderizing potatoes and melding flavors.

Step 7: Natural Pressure Release and Final Touches

When your timer beeps, allow a natural pressure release for 5 minutes, then manually release any remaining pressure before opening the lid. Remove and discard the bay leaf, then stir in fresh lemon juice for a vibrant finish. Taste and adjust salt or lemon juice as needed. The fish will gently break apart in the bowl, creating luscious textures.

Garnishes

Freshly chopped parsley and lemon wedges add an inviting burst of color and freshness to the bowl. Parsley lifts the savory notes, while lemon wedges offer guests the choice to brighten their stew even more with a squeezy of citrus. These simple touches make the meal feel special and cared for.

Side Dishes

While the stew is substantial on its own, serving it with crusty sourdough bread (if not avoiding gluten or Whole30) allows you to soak up every flavorful drop. For gluten-free or Whole30 meals, fluffy white or brown rice is the best companion, providing a comforting base that complements the stew’s bright medley perfectly.

Creative Ways to Present

For a fun twist, try serving this stew in individual oven-safe ramekins topped with a sprinkle of fresh herbs and a drizzle of olive oil, then broil briefly to add a golden crust on top. You could also garnish with a dollop of Greek yogurt or labneh for creaminess that cools down the vibrant spices.

Make Ahead and Storage

Storing Leftovers

You can store your Instant Pot Mediterranean-Style Fish Stew Recipe in an airtight container in the refrigerator for 3 to 5 days. The flavors actually deepen with time, making leftovers a real treat. Just give it a good stir before reheating to redistribute the fish and vegetables evenly.

Freezing

This stew freezes beautifully for 2 to 3 months. Use a freezer-safe container, leaving some space at the top since the liquid will expand. When you’re ready for a quick meal, thaw it overnight in the refrigerator for best texture, or defrost gently in the microwave.

Reheating

Reheat gently over low-medium heat on the stovetop or in the microwave, stirring occasionally until warmed through. Avoid boiling during reheating to prevent the fish from becoming tough. A splash of fresh broth or water can help loosen the stew if it has thickened in the fridge.

FAQs

Can I use frozen fish fillets for this recipe?

Absolutely! Just make sure to thaw them completely and pat dry before cooking to ensure the best texture and flavor in your Instant Pot Mediterranean-Style Fish Stew Recipe.

What type of fish is best for this stew?

Firm white fish like cod, haddock, or halibut work best because they hold their shape well during pressure cooking and have a mild taste that pairs wonderfully with Mediterranean herbs and spices.

Can I make this stew on the stovetop instead of an Instant Pot?

Yes, you can. Sauté your vegetables in a pot, add the liquids and seasonings, then simmer everything with the fish gently on top for about 15-20 minutes until cooked through. The Instant Pot just speeds up the cooking time with consistent results.

Is this recipe suitable for special diets?

Definitely! It’s easily adaptable for low FODMAP, Whole30, gluten-free, and paleo diets by selecting appropriate broths and side dishes. The focus on whole, fresh ingredients ensures it’s healthful for many eating styles.

How can I make the stew spicier if I like heat?

Add a pinch of red pepper flakes when sautéing the veggies or a dash of cayenne pepper with the dried herbs. You can also serve it with a spicy chili oil drizzle for guests who enjoy an extra kick.
