Ingredients You'll Need

A group of fresh vegetables and herbs are placed on a white marbled surface. There are four bright red tomatoes with smooth skin in the center, two green tomatillos with light green husks to the left, a fresh green chili pepper laid horizontally in front, a bunch of green cilantro with leafy texture to the right, and a whole green lime beside the cilantro. The colors are vibrant and the textures are fresh and natural, showing a simple arrangement of raw ingredients. photo taken with an iphone --ar 4:5 --v 7

The beauty of this salsa lies in its simplicity. Each ingredient plays a crucial role: tomatoes bring sweetness, tomatillos add tang and texture, and the serrano pepper offers a touch of heat, perfectly balanced by fresh cilantro and lime. Freshness and quality truly make all the difference here.

  • 4 vine ripe tomatoes: Choose firm yet juicy tomatoes for the best roasted flavor and natural sweetness.
  • 2 tomatillos: Remove the husks and sticky coating for a tart, citrusy punch that complements the tomatoes.
  • 1 serrano pepper: Adds a mild to moderate heat level—remove seeds if you prefer it less spicy.
  • ½ cup cilantro: Fresh cilantro brightens the salsa with herbal notes and vibrant green color.
  • ½ Spanish onion: Roasting mellows the pungency into a subtle sweetness that enhances the salsa.
  • 1 fresh lime or 3 tablespoon lime juice: Essential for balancing tanginess and tying all the flavors together.
  • 1 tablespoon vegetable oil: Coats the griddle and helps char the vegetables evenly without sticking.
  • ½ tablespoon kosher salt: Enhances natural flavors; adjust to taste after blending.

How to Make Roasted Tomato and Tomatillo Salsa Recipe

Step 1: Prepare and Clean Your Vegetables

Start by carefully removing the husks from the tomatillos and washing away the sticky residue—this step is crucial as the husks are inedible and the sticky layer can affect texture. Rinse the tomatoes, onion, and serrano pepper thoroughly to ensure a clean roasting experience. Removing the outer onion skin and halving it preps it perfectly for even charring.

Step 2: Heat the Griddle or Cast Iron Pan

Preheat your stove top griddle or cast iron pan over high heat until it’s scorching hot. A well-heated surface creates that beautiful char and smoky flavor that defines this salsa. Brush a thin layer of vegetable oil all over to prevent sticking and encourage caramelization of those delicious vegetables.

Step 3: Roast the Vegetables

Place the tomatoes, tomatillos, onion halves, and serrano pepper on the griddle. Let them cook undisturbed for about 5 minutes before turning. Keep rotating every few minutes until all sides are charred and the veggies soften, a process that takes about 30 minutes. You’ll hear the satisfying sizzle and popping as the skins blister—this is flavor magic in the making.

Step 4: Cool the Veggies

Remove the roasted vegetables from the heat and allow them to cool for around 15 minutes. Cooling helps the flavors settle and makes handling easier when preparing to blend, especially to safely remove stems and seeds.

Step 5: Blend the Salsa

Once cooled, cut off all stems from the vegetables and add them to your blender along with the fresh lime juice, cilantro, and kosher salt. Pulse in short bursts on medium speed until you reach a medium consistency—a few chunks are perfect for texture, but avoid large pieces for a smooth salsa experience. Taste and adjust salt as needed, keeping in mind tomatoes tend to absorb salt during roasting.

Step 6: Chill or Serve

For best flavor meld, refrigerate your salsa for 2 hours before serving. If you’re eager for instant gratification, enjoy it immediately at room temperature—the freshness and smoky notes will still shine brilliantly.

Garnishes

Enhance your salsa’s appeal with a sprinkle of fresh cilantro leaves or a few thinly sliced red onions on top—these brighten presentation and deepen flavor contrasts just perfectly.

Side Dishes

This salsa teams wonderfully with classic tortilla chips for dipping, but don’t stop there. It’s fantastic alongside grilled meats, roasted vegetables, scrambled eggs, or as a lively topping for tacos and burritos. It truly elevates any savory bite it accompanies.

Creative Ways to Present

Serve this roasted tomato and tomatillo salsa in a rustic earthenware bowl to complement its bold flavors and colors. You can also spoon it over avocado toast for a flavorful upgrade or use it as a fresh condiment layered within sandwiches or burgers to add smoky zing.

Make Ahead and Storage

Storing Leftovers

Keep leftovers in an airtight container in the refrigerator for up to 4 days. The salsa may thicken as it cools; simply stir before serving to bring back its vibrant texture and flavor.

Freezing

This salsa freezes beautifully. Portion it into freezer-safe containers or bags and store for up to 3 months. Thaw in the refrigerator overnight and give it a good stir before use to refresh the texture.

Reheating

Since this salsa is typically enjoyed chilled or at room temperature, reheating is not necessary. However, if you prefer it warm, gently heat in a saucepan over low heat until just warmed through—avoid boiling to maintain freshness.

FAQs

Can I use canned tomatoes instead of fresh ones for this Roasted Tomato and Tomatillo Salsa Recipe?

While fresh tomatoes offer the best flavor and texture for this salsa, canned tomatoes can be used in a pinch. Just roast them briefly or add a pinch of extra lime juice to brighten the flavor.

How spicy is this Roasted Tomato and Tomatillo Salsa Recipe?

The serrano pepper brings a gentle medium heat. If you prefer milder salsa, remove the seeds or substitute with a milder pepper like jalapeño or even omit it entirely.

Can I make this salsa without a grill or griddle?

Yes! You can roast the vegetables on a baking sheet under a broiler or use a hot cast iron skillet on your stove. The key is charring the vegetables evenly to develop those smoky flavors.

What is the difference between tomatillos and green tomatoes in this recipe?

Tomatillos are tart, citrusy fruits enclosed in paper-like husks, quite different from green tomatoes. They add a signature tang to the salsa that balances the sweetness of ripe tomatoes.

How long does the flavor improve if I refrigerate the salsa before serving?

Refrigerating the salsa for at least 2 hours allows the flavors to meld beautifully, enhancing both depth and balance, but it’s also delicious fresh if you’re short on time.

Final Thoughts

I can’t recommend this Roasted Tomato and Tomatillo Salsa Recipe enough if you love fresh, smoky, and vibrant flavors. It’s simple to make, uses wholesome ingredients, and elevates every dish it touches. Whether you serve it at a party or enjoy it on a quiet night in, this salsa will quickly become your go-to favorite. Give it a try—you’ll be amazed at how a few roasted veggies can create such magic!

This Roasted Tomato and Tomatillo Salsa is a vibrant, smoky, and slightly tangy salsa perfect for enhancing your favorite Mexican dishes or enjoying with chips. Roasting the tomatoes, tomatillos, serrano pepper, and onion on a hot griddle or cast iron pan brings out deep flavors and a subtle char that adds complexity to every bite. Blended to a medium chunky texture and chilled for two hours, this salsa is both refreshing and full of bold, zesty notes.

  • Total Time: 2 hours 40 minutes
  • Yield: 16 servings

Ingredients

Vegetables

  • 4 vine ripe tomatoes (or 2-3 larger ones)
  • 2 tomatillos (husks removed and sticky residue cleaned)
  • 1 serrano pepper
  • ½ Spanish onion (outside skin removed and cut in half)

Other Ingredients

  • ½ cup cilantro
  • 1 fresh lime (or 3 tbsp lime juice)
  • 1 tbsp vegetable oil
  • ½ tbsp kosher salt (plus more to taste)

Instructions

  1. Preheat the cooking surface: Heat a large griddle or cast iron pan on your stovetop or grill over high heat until very hot.
  2. Prepare vegetables: While heating the griddle, clean the tomatoes, tomatillos (remove husks and sticky residue), serrano pepper, and onion halves.
  3. Oil the griddle: Brush a thin, even layer of vegetable oil across the hot griddle to prevent sticking and help with charring.
  4. Roast the vegetables: Place tomatoes, tomatillos, onion, and serrano pepper on the griddle. Cook for about 5 minutes on one side.
  5. Turn and continue roasting: Flip the vegetables to cook the other side for another 5 minutes.
  6. Char evenly: Continue turning every couple of minutes, ensuring all sides develop a char and the vegetables soften; this process may take up to 30 minutes and will produce popping and sizzling sounds.
  7. Cool the vegetables: Remove from the heat and allow the roasted vegetables to cool for about 15 minutes.
  8. Trim stems: Cut off any stems from the tops of the vegetables to avoid tough bits in the salsa.
  9. Blend ingredients: In a blender, combine the roasted vegetables, fresh lime juice, cilantro, and kosher salt.
  10. Pulse to desired consistency: Pulse the mixture in 3-second intervals on medium speed until a medium chunky texture is achieved; adjust blending time for thicker or smoother salsa.
  11. Adjust seasoning: Taste and add more salt if needed, as tomatoes tend to absorb salt.
  12. Chill the salsa: Transfer salsa to a container and refrigerate for 2 hours for best flavor, or serve immediately at room temperature if preferred.
  13. Serve: Enjoy with tortilla chips or as a zesty accompaniment to your favorite savory dishes.

Notes

  • You can substitute lime juice with fresh lime for a brighter flavor.
  • Keep turning the vegetables carefully to get a good char without burning.
  • If you prefer a smoother salsa, blend for longer but avoid over-blending to preserve texture.
  • Adjust the level of serrano pepper or remove seeds for less heat.
  • Salsa can be stored in an airtight container in the refrigerator for up to 4 days.
