Spicy Mediterranean Swordfish with Tomatoes, Olives and Capers – Keto Low Carb Recipe

Keto Swordfish RecipeWe had this Mediterranean swordfish last week and the flavors were incredible. After doing some research I was inspired to make an Indonesian Italian fusion dish using the Serious Foodie Indonesian sauce. Fish dishes are prevalent in the Mediterranean and of course, you know I'm going to keep it low carb over here! This keto swordfish recipe for Calabrian Pesce Spada alla Ghiotta aka Spicy Swordfish with Tomatoes, Olives and Capers is similar to a traditional version, but without the higher-carb ingredients like raisins or crostini.

I'm so glad this recipe contest forced me to get even more creative than usual. This spicy swordfish recipe is going to rock your world! No seriously, hubs claimed it's one of my best in a while.

Mediterranean Swordfish from the Calabria Region

This recipe for spicy swordfish or Calabrian Pesce Spada alla Ghiotta is a dish from the Italian region of Calabria. There are many variations that have a varying amount of carbs. So many Italian dishes have tomatoes and onions which are absolutely delicious. However, if you're trying to keep your carb count in the 20 to 50 grams a day range, these types of ingredients add up.

You still have to watch the carb count even when ingredients are from a keto-friendly, whole foods source. This is where it can be useful to test yourKeto Swordfish Recipe personal carb tolerance with a meter like Keto Mojo. My body tolerates more carbs, typically as long as they're from whole food sources. As long as the vegetable isn't overly starchy like potatoes, I do fine with them.

I used lots of ingredients that are common in Mediterranean cooking as well as a few that aren't. Pinenuts always add a great crunch. Along with olives and capers, this makes a great flavor combination. Peppers are more common in Indonesian cooking so I wanted to include some here.

I don't know if  Italian Indonesian fusion is a thing, but I'm calling it one now! I had to go with what was on hand, peppadew peppers but if you can find Sambal (like the peppers used in the sauce) or cable pepper those would make great additions to this dish.

If you happen to know you can tolerate a few extra carbs, go ahead and use the whole 14 ounces can of diced roasted tomatoes. Swordfish is very sturdy and holds up well to grilling. The grill marks are great for presentation.

However, if it's too cold where you are or you just prefer to use your cooktop to sear the fish, that works just as well.  Swordfish is very keto-friendly and a great source of protein. An eight-ounce swordfish steak provides 390 calories,  no carbs, 53 grams of protein and 18 grams of fat. However, it can have high mercury levels so best to keep consumption to once a week or less.

For this keto swordfish recipe, I also had to adjust the ingredient amounts somewhat to adjust to a two-serving dish. However, I'd recommend making a double batch of this sauce and freezing some to use for later. It would be delicious with any mild white fish and if you adjust the sauce amount to smaller servings, you can easily adjust the macros of this dish to be even lower carb and less calories.
