This roasted red pepper dip is exactly the kind of recipe I love keeping in the fridge because it makes everything taste better. I’m someone who likes bold, savory flavors, and any appetizer that is garlicky, smoky, and easy to use a teaspoon to put onto a sandwich gets my attention immediately.

If you enjoy dips like hummus or whipped feta, you’ll probably love this San Marzano Pizza Sauce too. But this roasted red pepper dip has that deeper roasted flavor that feels a little more special.

Try This Easy Roasted Red Pepper Dip

I like recipes that take very little effort, the ingredients are easy to purchase, and can be eaten by tablespoons. This one does exactly that.

Once the peppers roast and blend with the other ingredients, you get a rich, creamy dip that tastes like something from a really good café platter.

What Is Roasted Red Pepper Sauce Dip?

Roasted red pepper dip is a blended savory dip made with roasted peppers, garlic, olive oil, bread, nuts, and seasonings. You can add onion too if you like.

This good dip is inspired by romesco, so it has a smoky, nutty, slightly tangy flavor that works with almost anything. Make sure you make enough, as I doubt there will be any leftover dip available once you try it!

Why You’ll Love This

• Super easy: I love how simple the air fryer makes roasting the peppers.
• Big flavor: Smoky peppers, garlic, and almonds work beautifully together.
• Perfect Texture: Smooth, full of creaminess, and great for dipping or spreading.
• Versatile: I use this easy snack made from simple ingredients with bread, chicken, in a wrap, on crackers, and vegetables.

Ingredients

romesco sauce ingredients
  • Red Ramiro sweet peppers: The star of the dip with natural sweetness once roasted.
  • Almonds: Gives body and nuttiness.
  • Garlic: Adds bold savory flavor.
  • Bread: Helps thicken the dip and gives texture.
  • Tomato: Adds freshness and depth.
  • Olive oil: Makes everything rich and silky.
  • Red wine vinegar: Gives brightness and balance.
  • Paprika & basil: Adds warmth and extra flavor.

How to Make Roasted Red Pepper Dip

1. Preheat the air fryer to 400°F (200°C).

2. Rinse the Ramiro peppers, remove the seeds, and cut them into pieces.

3. Place the peppers in your air fryer basket with the skin facing up and roast for about 20 minutes. The pepper skin might be charred in some spots, which is perfectly normal.

4. After 20 minutes, remove the peppers and place them in a large bowl with a lid. Let them cool for 20-30 minutes. This will make it easy to peel off the skin.

5. While the peppers are cooling, place the halved tomato, a garlic clove, and a slice of bread on the bottom of the air fryer basket. Roast for approximately 5 minutes or until the bread has a golden crust.

6. Once done, remove the bread, garlic, and tomato from the air fryer.

7. Remove the tomato skin and place the roasted tomato in the blender cup along with the garlic, bread, all the remaining spices, olive oil, and vinegar.

8. Take the peppers out of the bowl and peel off the skin. If you don't like the charred edges of the peppers, you can trim them with a knife. Place the peppers in the blender cup as well.

10. Transfer the sauce to a storage container and refrigerate for 30 minutes before consuming. You can also use the sauce immediately if you wish.

Recipe Tips

  • Ensure your peppers are dry after rinsing to prevent steam from forming in the air fryer, which could hinder that desirable char.
  • When arranging the peppers in the air fryer, give them ample space to ensure even roasting and avoid overcrowding.
  • Be mindful of the garlic when roasting them alongside the tomato. They may require a quick check midway to prevent burning due to their smaller size.
  • Peeling the peppers becomes a breeze when you allow them to cool in a covered bowl, as the steam helps loosen the skin.
  • When blending, start at a lower speed to ensure all ingredients are smoothly incorporated before ramping it up for a velvety finish.

NOTE: While muhammara is another Mediterranean-style dip made with roasted red peppers, it traditionally includes walnuts and breadcrumbs. This version skips both, though many of the other flavors overlap.

FAQs About My Easy Romesco Sauce

​​​​What is romesco sauce made of?

Romesco sauce is a flavorful Spanish condiment primarily made from roasted red peppers, garlic, almonds or hazelnuts, olive oil, and vinegar. It often includes tomatoes, bread or breadcrumbs as a thickener, and seasonings like smoked paprika.

What is the difference between Romanesco and Romescos?

Romanesco refers to a unique, fractal-patterned vegetable that's a hybrid between cauliflower and broccoli, whereas Romescos pertains to the rich and nutty Spanish sauce made primarily from roasted red peppers and nuts.

What goes well with romesco sauce?

Romesco sauce pairs wonderfully with grilled meats, roasted vegetables, fish, and poultry. It's also delightful as a dip for bread or spread for sandwiches.

What is the best method for roasting peppers?

The air fryer proves to be a splendid method for roasting peppers, providing a perfect char and smoky flavor without the mess and constant attention required by other methods.

Is it better to roast or fry peppers?

Roasting peppers, especially in an air fryer, is often preferred over frying due to the reduced oil usage and the ability to achieve a smoky char without splattering oil, offering a healthier and cleaner cooking experience.

Can I still use the sauce if the peppers are too charred?

Yes, you can still use slightly over-charred peppers, as they will add a smoky flavor to the sauce. However, if they are burnt to a crisp or have a bitter taste, it’s best to discard them to avoid affecting the overall flavor of the sauce.

My sauce tastes too acidic or bitter; how can I balance the flavors?

To balance an overly acidic or bitter sauce, consider adding a pinch of sugar or a drizzle of honey. You can also add a splash of olive oil or a small amount of roasted nuts to help mellow out the acidity and enhance the richness of the sauce.

Can I make this recipe without an immersion blender?

Certainly! While an immersion blender makes the process smooth and easy, you can use a regular countertop blender or a food processor. Just ensure to blend in batches if needed and be cautious with hot ingredients to prevent splattering.

The sauce separated after a few days in the fridge, is it still good to use?

If the sauce separates, it’s typically still safe to use. Simply give it a good stir to recombine the ingredients. However, always check for any signs of spoilage, like an off smell or mold, before using.

Can I use pre-roasted jarred peppers for this recipe?

Yes, pre-roasted jarred peppers can be a time-saving alternative. Just be sure to drain and possibly rinse them to remove excess vinegar or brine, and pat them dry before using them to maintain the intended flavor profile of the sauce.

Equipment

  • Air Fryer
  • Immersion blender with a cup
  • Knife
  • Cutting board
  • Large bowl with a lid
  • Sauce storage container
  • Cooking tongs
  • Silicone spoon

Ingredients
  

  • 2 ramiro sweet pepper (also known as pointed peppers)
  • 2 tablespoon almonds
  • 1 clove garlic
  • 1 slice bread
  • 1 tomato
  • 2 tablespoon olive oil
  • 2 tablespoon red wine vinegar
  • 1 teaspoon paprika
  • 1 teaspoon dried basil
  • ½ teaspoon salt
  • ½ teaspoon pepper

Instructions

  • Preheat the air fryer to 400°F (200°C).
  • Rinse the Ramiro peppers, remove the seeds, and cut them into pieces.
  • Place the peppers in your air fryer basket with the skin facing up and roast for about 20 minutes. The pepper skin might be charred in some spots, which is perfectly normal.
  • After 20 minutes, remove the peppers and place them in a large bowl with a lid. Let them cool for 20-30 minutes. This will make it easy to peel off the skin.
  • While the peppers are cooling, place the halved tomato, a garlic clove, and a slice of bread on the bottom of the air fryer basket. Roast for approximately 5 minutes or until the bread has a golden crust.
  • Once done, remove the bread, garlic, and tomato from the air fryer.
  • Remove the tomato skin and place the roasted tomato in the blender cup along with the garlic, bread, all the remaining spices, olive oil, and vinegar.
  • Take the peppers out of the bowl and peel off the skin. If you don't like the charred edges of the peppers, you can trim them with a knife. Place the peppers in the blender cup as well.
  • Blend all the ingredients.
  • Transfer the sauce to a storage container and refrigerate for 30 minutes before consuming. You can also use the sauce immediately if you wish.

Notes

Tip: Add a little boiled water if the mixture is too thick for your preference. The thickness depends on the juiciness of the peppers. Keep in mind that Ramiro peppers are not as juicy as bell peppers. I prefer a thicker sauce, but if you want a thinner consistency, add a little more water.

Cooking Time and Temperature

Setting the air fryer to 400°F (200°C) gives the peppers a lovely roast with a little char.

Serving Recommendations

  • Drizzle it over grilled chicken or fish for a Mediterranean flair.
  • Use it as a vibrant dressing for your salads, adding a burst of flavor that makes every bite memorable.
  • Don’t shy away from spreading it on your sandwiches or wraps, as it adds a gourmet touch that’s simply irresistible.
  • Consider it as a dip for your crusty bread, veggies, or pita chips during snack time or gatherings, and watch it disappear in no time!

Recipe Variations and Substitutions

  • While Ramiro peppers bring a unique sweetness to the sauce, feel free to experiment with different types of peppers to play around with flavors and heat levels.
  • If almonds aren’t your nut of choice, substituting them with hazelnuts or cashews can offer a delightful twist to the traditional recipe.
  • If you're seeking a nut-free option, roasted sunflower seeds can replace the almonds.
  • For a gluten-free version, replace the bread with gluten-free bread or even some cooked rice to maintain the thickness.
  • If you’re looking to add a spicy kick, consider throwing in a dash of cayenne pepper or a small piece of a hot chili pepper into the blend.
  • For a vegan twist, you might explore using a vegan-friendly bread and ensuring all other ingredients align with your dietary preferences.

Proper Storage Tips

  • Pour the sauce into an airtight container and it can happily keep in your refrigerator for up to 3-4 days.
  • If you’ve made a larger batch and want to preserve some for later, freezing is a fantastic option. Just portion the sauce into freezer-safe containers or ice cube trays for easy future use.
  • Always ensure to use a clean spoon when scooping out the sauce to prevent contamination and prolong its shelf life.
  • When ready to use the frozen sauce, simply thaw it in the refrigerator overnight or gently warm it up on the stove.

Taste & Texture

Creamy, smoky, nutty, and slightly tangy with rich roasted pepper flavor.

Pro Tips

  • Roast peppers until slightly charred.
  • Peel after steaming.
  • Blend to your preferred texture.
