Step-by-Step Instructions

This is a straightforward recipe that comes together in stages. Each step builds on the last, and before you know it, you’ll have a restaurant-quality meal ready to serve.

Step 1: Sauté the Aromatics

Melt butter in a large oven-safe skillet over medium heat. Add minced garlic and cook for about 1 minute, stirring often, until fragrant. Don’t let it brown, just let it wake up in the heat.

Step 2: Add the Sundried Tomatoes

Stir in the chopped sundried tomatoes and cook for another minute. You’re building layers of flavor here, and this is where the magic starts.

Step 3: Create the Sauce

Pour in the heavy cream and chicken broth, stirring to combine. Add the Italian seasoning, salt, pepper, and red pepper flakes if using. Bring the mixture to a gentle simmer and cook for 2-3 minutes until slightly thickened.

Step 4: Wilt the Spinach

Stir in the fresh spinach and let it wilt into the sauce, about 1-2 minutes. The spinach adds nutrition and color without being fussy about it.

Step 5: Nestle in the Fish

Gently place the tilapia fillets into the simmering sauce, spacing them out so they cook evenly. The fillets don’t need to be fully submerged, just nestled into the sauce.

Step 6: Bake Until Cooked Through

Transfer the skillet to a preheated 375°F oven and bake for 18-22 minutes, until the fish flakes easily with a fork and the flesh is opaque all the way through. The tilapia cooks fast, so keep an eye on it after 18 minutes.

Step 7: Garnish and Serve

Remove from the oven and top with fresh basil or parsley if you have it. Serve the tilapia right in the skillet or plate it individually with plenty of that creamy sauce spooned over the top.

Pro Tips & Tricks

A few small adjustments make this dish even better the next time you make it.

Tilapia fillets are delicate, so handle them gently when placing them in the skillet. You don’t need to flip them, the oven does all the work. If your fillets are thicker than usual, they may need an extra 2-3 minutes in the oven, so adjust based on thickness.

Make sure your skillet is oven-safe before you pop it in the oven. A regular non-oven-safe skillet won’t work here. If you don’t have an oven-safe skillet, you can transfer everything to a baking dish instead, no problem.

Fast Fact: Tilapia is one of the fastest-cooking fish fillets, which is why it’s perfect for weeknight dinners. Most fillets cook through in under 20 minutes.

Storage Tips

This dish is best enjoyed fresh, but it stores well if you have leftovers.

Store any leftover tilapia and sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently in a 325°F oven for about 10 minutes, or in a skillet over low heat on the stovetop. The fish may be more delicate after reheating, so handle it carefully.

You can also freeze the dish for up to 2 months, though I recommend eating it fresh to enjoy the delicate texture of the fish at its best.

Frequently Asked Questions

Can I use frozen tilapia? Yes, absolutely. Thaw the fillets completely in the refrigerator before cooking, and pat them dry with paper towels to remove excess moisture. Dry fish cooks more evenly.

Can I substitute the heavy cream? You can use half-and-half, but the sauce won’t be quite as rich. Greek yogurt works too, but add it at the end after removing from heat so it doesn’t curdle.

What if I don’t like sundried tomatoes? Swap them for diced fresh tomatoes, roasted red peppers, or even artichoke hearts. The sauce is versatile and forgiving.

Can I cook this on the stovetop instead? You can reduce the oven time to 15 minutes and cover the skillet with a lid instead of transferring to the oven. Watch for the fish to cook through, keeping the heat at a gentle simmer so the sauce doesn’t splash.
