A New Way to Fish – Rosemary Potato Crusted Tilapia with Basil Oil
June 25, 2011 § 2 Comments
I really do love fish and I’m always looking for new ways to prepare it. I prefer salmon, grouper, and of course, sea bass, but sometimes you just need an economical alternative. Enter, tilapia. I’ve never really been a big fan of tilapia – I’ll eat it and I don’t mind it but I’ve never craved it. My husband has developed a strong liking for it so I’ve been looking for new ways to prepare it. So far, simply grilled with a little olive oil, salt, pepper, and a splash of lemon has been a good way to go. Another option is sauteed with a light flour coating and finished in a parsley butter sauce. I recently saw a recipe by Giada de Laurentis for a potato crusted tilapia that looked amazing. I’m in for any recipe that involves a potato! Giada’s version called for purple potatoes and a chive basil oil. I was making this for a nice little Sunday lunch at home so I had to deal with what I had on hand – no purple potatoes or chives, but I did have new potatoes and some fresh basil.
This dish is surprisingly easy and produces a really elegant meal that takes fish to a whole new level. Giada’s recipe calls for a mandolin for super thin potato slices – I don’t have a mandolin so I just sliced the potato as thinly as I could manage. This worked fine but I think a mandolin would have helped produce a bit crispier potato which would have been delicious. However, if you don’t have a mandolin, don’t fret – just slice thinly and you’ll still be enjoying deliciously sauteed potatoes.
Once the potato slices are done, assembly is very easy. Season the tilapia with salt and pepper and then top with the potato slices. A little more salt, pepper, and some rosemary and the fish is ready to go. In an oven-proof skillet heat equal parts butter and olive oil over medium high heat. You want the skillet to be pretty hot so it gives a nice sizzle to the potatoes. I thought getting the fish potato side down into the skillet was going to be tricky but it actually turned out to be pretty easy. I found that placing my spatula over the fish and then flipping it potato side down and sliding out the spatula worked best. Once the fish is in, you pop it into a a 375 degree oven for about 15 to 17 minutes until the fish is cooked through.
While the fish cooks, make the basil oil. Simply mix chopped basil and olive oil together and a little salt and pepper and set aside. I added some more rosemary to the oil and happened to have some roasted garlic on hand which I mashed into the oil as well for a little extra flavor.
Once you remove the fish from the oven, flipping over to serve potato side up is quite tricky. After a few tries, a food scraper proved to be the best way to accomplish the task – carefully slide it under the potato while holding the top of the fish with a spatula and flip. The potato doesn’t actually stick to the fish so if it’s not held together it will fall apart. Top the fish with some basil oil and serve. I found a generous squeeze of lemon finished the fish nicely, but you could try it first without and see what you think.
As I’m coming to find – I like my own cooking a lot more than what I find in restaurants. I can assure you, you’ll like this dish and it will be very different than anything you’ll see in a restaurant – at least from what I’ve seen. Enjoy!
