Bratwursts deserve something feistier than relish or a zucchini pickle, so I am sharing my recipe for quick pickled sweet peppers with shallots and thyme. This reminds me of Italian giardiniera, and my grandmother’s refrigerator pickles, but is just the zesty, vinegary topping that every good sandwich, homemade pizza, or brat needs.

A Bratwurst’s Best Friend

I have been on a non-stop grilling kick for over two weeks now, charring up and sizzling everything from fresh red peppers and eggplants to perfect grilled steak and rock shrimp. I don’t care what anybody says: a homemade, grilled dinner is so much more enjoyable since it’s less than half the cost of a restaurant in downtown Charleston!

I wanted a brat in a bun this week so badly, but they wouldn’t be complete without a hot-n-sweet pickle of some sort to accompany the condiments and diced onions. A brat is a stand-alone quasi sandwich whose toppings need to be as stand alone as it does, and these pickled peppers with shallots fit the bill perfectly!

Ingredients

Assorted mini sweet peppers, shallots, garlic, fresh thyme, jars of salt and spices, and a measuring cup of water on marble.

Curious what ingredients you need to whip up these pickled peppers and shallots? Grab these key ingredients, along with a few others, and you’ll be ready to make these in no time!

  • Sweet Peppers: Move over jalapeno, use mini sweet peppers or simply cut red, orange, and yellow bell peppers into wide strips. These sweet peppers have a great flavor that only gets better once they’re pickled.
  • Shallots: This mild aromatic is even better when pickled than onions are! If you can’t find shallots, try using a sweet onion instead.
  • Vinegar: You’ll need 2 cups of distilled white vinegar. This ingredient is easy to find at your local grocery store and makes the perfect vinegar liquid for pickling. The acidic nature keeps bacteria from growing in the pickles, and it brings a punchy flavor that’s just right.
  • Thyme: I recommend using a small bunch of fresh thyme to add a wonderful flavor to the pickled peppers. You can substitute with a different herb (like rosemary) if you prefer.

See recipe card for full information on ingredients and quantities.

Variations & Substitutions

  • Alternative Pepper Varieties for Pickling: If you want more heat, use a mixture of sweet bell peppers, Italian peppers, banana peppers, jalapeños, or pepperoncini.
  • White Wine Vinegar may be substituted for distilled white vinegar for a more pungent bite.
  • Adjust the Sweetness or the Spice: For a sweeter pickle, add a bit more sugar or a splash of honey. For spicy pickled peppers, toss whole peppercorns, mustard seed, cayenne, and even a fresh chili pepper sliced down the side.
  • Can’t Find Shallots? Use thinly sliced red onion or sweet onion instead.

Recipe FAQs

What do you put in pickled peppers to keep them crisp?

For extra-crisp pickled peppers, add a couple of crumbled bay leaves to each jar. The tannins from the leaves will help the pickled peppers stay crunchy as they sit in the brine.

Are shallots good for pickling?

Yes, shallots are excellent for pickling! Some people actually like shallots better than regular onions when they’re pickled. I think they pair perfectly with this sweet peppers.

Which vinegar is best for pickled peppers?

It’s best to use distilled white vinegar for pickled peppers and shallots. It’s easy to find and brings a strong flavor that’s perfect for pickled veggies.

How long do pickled sweet peppers last?

When sealed properly in mason jars, pickled sweet peppers will stay fresh in the fridge for several weeks. This particular recipe is not meant to be shelf-stable, so you shouldn’t keep it at room temperature in the pantry. As with any pickling project, always check the jar lid and seals before eating, since a broken seal can shorten storage time.

Do you have to water bath pickled peppers?

Seasoned home canners often reach for a water bath canner when making shelf-stable pickles. However, this recipe is designed for refrigerator storage, not long-term pantry storage. The jars and brine still benefit from proper filling—avoiding air bubbles and ensuring a tight jar lid seal—but the finished peppers are meant to be kept chilled rather than processed for room temperature keeping.

Serving Suggestions

These tangy and sweet pickled peppers are by no means a topping for a bratwurst alone, so be creative! These make a wonderful addition to hearty sandwiches like buttermilk crispy chicken sandwich, Alabama chopped chicken sandwich, or leftover beef tenderloin sandwiches. Or enjoy on salads, cheeseboards, grilled bratwurst, hot dogs, hamburgers, or any grilled meat.

Expert Tips

  • Aim for uniform thickness and size when cutting the shallots and peppers so they pickle evenly.
  • Don’t skip the salt. It’s not just about flavor; salt preserves the pickles and keeps them crisp and flavorful.
  • Use very clean jars to prevent any bacterial growth, to preserve freshness, and to extend its shelf life in the fridge. Wash in very hot water with soap and rinse well, or run the jar through the dishwasher.
  • Chill the pickles for at least 24 hours before serving. For an even more vinegary flavor, wait 3-4 days.

    1. Char, they are best after “curing” for 2 to 3 days and eaten within 12 days after curing. When it feels like they are getting slightly soft, I chop them into relish for brats and hot dogs after that and try to eat it up 🙂 Jenny
