🌶️ Simple Red Pepper Onion Relish Recipe (30 Minutes)

This easy relish recipe makes enough for 4-6 servings and requires just 8 basic ingredients. No special equipment needed!

Basic Ingredients:

• 4 red bell peppers, finely chopped
• 2 red onions, finely chopped
• 1-2 jalapeños (optional for heat)
• 3 garlic cloves, minced
• ¼ cup apple cider vinegar
• 2 tbsp olive oil
• 1 tbsp sugar
• Salt and pepper to taste

Simple Instructions:

1. Chop peppers, onions, and jalapeños into small, even pieces
2. Heat olive oil in a skillet over medium heat
3. Add onions and peppers; cook for 10 minutes until softened
4. Add garlic, vinegar, sugar, salt, and pepper
5. Cook for 15-20 more minutes until thickened
6. Let cool before serving or storing

Why This Easy Relish Recipe Works

Most relish recipes fail because they either become too watery or lose flavor quickly. This version succeeds because:

• Perfect ingredient ratio: 2:1 pepper-to-onion ratio creates balanced flavor
• Right cooking time: 20 minutes simmering removes excess water without losing texture
• Vinegar amount: Just enough for tang without overpowering the fresh pepper taste
• Simple spice mix: Salt and pepper enhance rather than mask the natural flavors

This relish tastes great immediately but actually improves after 24 hours as the flavors meld together.

How to Store Homemade Relish Properly

Want your relish to stay fresh for weeks? Follow these simple storage tips:

• Refrigerator storage: Keep in airtight container for up to 3 weeks
• Long-term storage: Process in sterilized jars for pantry storage up to 3 months
• Freezing option: Freeze in ice cube trays then transfer to freezer bags (keeps 6 months)
• Signs of spoilage: Discard if you see mold, smell anything sour, or notice texture changes

3 Common Relish Mistakes to Avoid

Even experienced cooks make these relish mistakes:

• Chopping ingredients too large: Small, uniform pieces (about ¼ inch) ensure even cooking and texture
• Skipping the cooling time: Let relish cool completely before storing to prevent condensation and spoilage
• Using wrong vinegar: Stick with apple cider or white vinegar (5% acidity) for proper preservation

Frequently Asked Questions

Here are answers to other common relish questions:

• Can I use bell peppers of different colors? Absolutely! Mix red, yellow, and orange peppers for a colorful relish with slightly different flavor notes.
• Do I need to peel the peppers? No need to peel - the skins soften during cooking and add texture and nutrients.
• How can I make it less spicy? Remove all seeds and white membranes from jalapeños, or substitute with milder peppers like poblanos.
• Can I can this for shelf-stable storage? Yes! Process filled jars in a boiling water bath for 10 minutes for safe pantry storage up to 1 year.
• Why does my relish separate? Separation happens when not cooked long enough. Simmer until thickened, stirring occasionally.

How long does homemade relish last in the refrigerator?

Properly stored in an airtight container, homemade relish will stay fresh in the refrigerator for 3-4 weeks. Always use clean utensils when serving to prevent contamination.

Can I make this relish without sugar?

Yes, you can omit the sugar or use a sugar substitute. The relish will be more tangy. For best results, start with 1 tsp and adjust to your taste preference.

Why is my relish watery?

Watery relish usually means it didn't cook long enough to reduce the liquid. Next time, cook 5-10 minutes longer on medium-low heat. Also, make sure to chop ingredients uniformly for even cooking.

Can I freeze homemade relish?

Yes! Freeze in ice cube trays, then transfer to freezer bags. Properly frozen relish maintains quality for 6 months. Thaw in refrigerator before using.

What's the best way to use leftover relish?

Beyond sandwiches, try relish as a topping for grilled meats, mixed into tuna/chicken salad, stirred into cream cheese for a dip, or as a side with scrambled eggs.
