What does swordfish taste like?
Not too fishy and bland, a perfect combination of flavor and texture. Not to mention that you can prepare it in so many ways.
Mild tasting with a meaty white-flesh fish. Primarily sold in steaks form. A great choice of fish to enjoy if you have a fussy fish eater in your house.
Is swordfish an excellent fish to eat?
However, due to high levels of mercury, it is advised to eat small portions and not too frequently as you would any other shellfish low in mercury.
Roasted bell peppers: fresh or jar?
When the bell peppers are in season, I highly recommend using fresh bell peppers. The flavor is out of this world.
When not in season, you can skip a few steps of this recipe by using prepared roasted bell peppers.
Dry them well once out of the jar to remove any oil or liquid they were preserved into.
Double or triple this recipe to have on hand. Excellent with pasta, rice, omelets, salads, and much more.
Bell peppers are a great source of vitamins C, B6, K1, E, and A and are low in calories.
Here are a few helpful tips for the ingredients needed to make these delicious Swordfish with Onions and Roasted Bell Peppers recipe
This is a quick introduction. Please read the recipe for complete instructions.
Bell peppers: Red, orange, and yellow. They are milder and give a beautiful array of colors to your dish.
Yellow onion: sweeter than your regular onions. Do slice them very thinly. You can use white onion if you have those on hand.
Garlic: everything tastes better with garlic.
Capers: a great source of saltiness and flavor.
Chardonnay vinegar: Great acidity content to uplift your vegetables with a balance.
Cumin, red pepper flakes, and coriander: all the combined spices work well with the sweetness of the roasted bell peppers.
Swordfish: the star of your dish, skin on, of course.
Olive oil: to bind the vegetables.
I only recommend what I use and love.

Cooking tips and steps by steps to achieve this excellent swordfish with onions and roasted bell peppers recipe:
The longest part of the cooking process is roasting bell peppers. On the bright side, you can take advantage of this step and make some extra bell peppers that you can store with olive oil and use later.
Roasting the bell peppers:
Easy step and a bit time-consuming. Make sure your oven is well-preheated.
Strongly suggest placing a sheet of parchment paper. This will eliminate the peppers from attaching themselves to the cookie sheet.
I do not know about you, but I wouldn’t say I like extra cleaning if I can avoid it.
- Rub the peppers well evenly with olive oil.
- Once in the oven, pay close attention to them and rotate them more than once, if need be, to ensure all sides are well charred.
- Once done, remove and place the peppers in a large bowl. Seal well with plastic wrap. Sealing them allows all the moisture to stay inside the bowl, and this step will facilitate the removal of the outer peel faster and easier.
- Discard of all the internal seeds, and stem during the outer skin removal.
- Slice them into strips
Preparing the other ingredients
- Use white vinegar as it is lighter in flavor than red wine vinegar. Chardonnay or champagne is mild and gives an extraordinary hint in the background.
- Red, yellow, or orange bell peppers as they are milder in flavor than unripe green bell peppers. They are my preference for this dish.
- Chop some of the capers and leave some intact. Using under salt capers is idyllic but not necessary. Which one you may choose, rinse them before adding them to the onion bell peppers mixture.
- Vidalia onions are my favorite as they caramelize best, and I enjoy their sweetness.
- Do not burn the garlic slivers.
I am well aware of the amount of garlic used in this dish. Noteworthy, you will love it.
Gently cooked with the onions for a few seconds and the vinegar and capers, the combination is out of this world.
The bell peppers are more on the sweet side. They balance well with the garlic.
Substitutions for the swordfish
Cod, salmon, halibut, or red snapper can be substituted instead of the swordfish in this recipe.
