These Sardine Stuffed Mini Peppers Will Have You Hooked!

I’m REALLY excited about this recipe. It brings together so many potent flavors that are bold on their own. Yet together, instead of being overwhelming, they sing!

And baked, blistered mini peppers make for the perfect vessel to stuff them in. They’re crunchy, creamy, and light enough to be the perfect summer appetizer.

They’re also quite pretty!

An Easy Ingredient List.

Big flavor doesn’t necessarily mean more ingredients, and that’s what I love about this recipe. We’ve got creamy goat cheese folded into a mix of onions, garlic, mushrooms, olives, capers, and King Oscar’s brisling sardines in extra virgin olive oil, and it’s exquisite.

Here’s what t0 throw on your grocery list:

  • King Oscar Brisling Sardines in Extra Virgin Olive Oil
  • Red Onion
  • Mushrooms
  • Garlic
  • Caper berries
  • Kalamata olives
  • Goat cheese
  • Panko bread crumbs
  • Lemon
  • Fresh parsley

King Oscar Brisling Sardines Are a Treat.

Even if you don’t think you like sardines, you might. You JUST might.

Believe it or not, canned sardines are incredibly versatile–which you’ll see by checking out these canned sardine recipes. They can be added to so many different dishes, from this melty gourmet grilled cheese with sardines to this Instant Pot pesto pasta with sardines. And they pack a healthy punch!

King Oscar’s sardines are especially a treat because of their quality. They’re handled with care and hand-packed with high quality ingredients, and they’re sustainable!

Good for you and good for the planet—that spells win/win.

How to Make These Sardine Stuffed Mini Peppers.

Appetizers should be easy. They’re a warm-up and should be treated as such.

This recipe includes minimal chopping, a little mixing, some scooping, and some baking. That’s it!

Here’s what you’ll do:

  1. Get your oven preheated to 375º F.
  2. Heat olive oil (you can use the olive oil from the tin of sardines!) in a pan over medium heat. Add the onions, mushrooms, and garlic to the pan and let them simmer for about 2 minutes, until softened.
  3. Add the capers, olives, and sardines. Simmer and break down the caper berries with your spatula or spoon as your stir. After about a minute, remove the pan from the heat. Transfer the mixture to a mixing bowl and add the goat cheese. Stir until the cheese melts into the mixture and everything is well blended; set it aside.
  4. Place the peppers, open side down, on a cast iron pan. Brush the backs of the peppers with a bit of olive oil and flip them over. Then scoop the mixture into the peppers until completely filled.
  5. When filled, sprinkle panko breadcrumbs over the peppers, pop them into the oven, and bake for about 20 minutes.
  6. Remove the peppers from the oven, and sprinkle the lemon zest and some fresh chopped parsley on to. Hit those suckers with some fresh lemon juice and dig in!

Recipe Tips + Tricks.

  1. If goat cheese isn’t your jam, you could replace it with cream cheese.
  2. I like using big caper berries in this recipe, but regular small capers will work just fine.
  3. If your panko topping hasn’t turned a nice golden color after baking for 20 minutes, pop it under the broiler for a few minutes! Just be sure to keep a close eye on it so they don’t burn.
