A great way to add extra flavor to your salsa is to roast or char the vegetables before you blend them, but did you know you can achieve a quick and easy char right in your pizza oven?

The reason pizza ovens are so great for charring vegetables is they are able to reach high temperatures quickly, and the Ninja Woodfire Outdoor Oven is a great tool for the job.

One of the excellent features of the Ninja Woodfire Outdoor Oven is that you can add wood pellets to enhance the flavor with real woodfire smoke flavor.

How to Make Roasted Red Pepper Salsa in a Pizza Oven

1. Fire up the oven

To get the Ninja Woodfire Outdoor Oven fired up, all you have to do is add pellets to the grill, set it to the ‘Specialty Roast’ setting, and press the ‘Woodfire Flavor’ button while it preheats.

It will ignite the pellets first to get the woodfire flavor started, then will automatically start preheating the oven to 650°F.

2. Prep

Chop the stems off of the bell peppers and jalapeños, then slice the onion into quarters. Remove the seeds from the bell pepper, but leave them in the jalapeño to add a nice punch of spice. If you prefer milder salsa, simply remove the seeds from the jalapeño as well.

Place your chopped vegetables in a small baking pan, and they’re ready to hit the oven!

You can alternatively roast the tomatoes and garlic as well, it’s all about personal preference.

There are a lot of ways to make salsa, and everyone has their own preferences.

I like to roast bell peppers, onions, and jalapeño in the oven, but I prefer to keep the garlic and tomatoes raw. You get an extra punch of acidity from the tomatoes, and the raw garlic flavor really pulls the salsa together.

3. Roast

Once your oven is preheated, you can simply place the baking dish full of vegetables inside.

Since you are cooking at a high temperature (650°F), the vegetables won’t take long to get a nice char on them.

I let mine roast for about 6 minutes, and they were perfect, but just start checking them after about 5 minutes and pull them out when they are charred to your liking.

4. Blend

Once you’ve removed your roasted vegetables from the pizza oven, add them to a blender or food processor. Add the fresh tomatoes, garlic, cilantro, water, a squeeze of lime to taste, and Kosher salt, then blend it to your desired consistency.

If you prefer a thicker salsa, skip the water and just pulse the vegetables. If you prefer a thinner salsa, keep the water in the recipe and blend until fully smooth.

Once your salsa is blended, you can serve it immediately or let it cool in the fridge for a few hours and serve it cold. It does get better with time!

It goes great on tacos, tostadas, and all types of foods, but you can also serve it alongside tortilla chips as the perfect dip.

It will keep in the fridge for up to 7 days in an airtight container or jar.
