Why we love Roasted Tomato & Red Peppers Pasta Sauce

As you can tell, we love this recipe. I mean, I have been making this only for about a decade now.

Here is why!

  • Loaded with vegetables -Has insane amount of veggies AND you can add more!(No body will know!)
  • It's cheaper than any jarred sauce. Especially in places you can get fresh tomatoes.
  • Same sauce can be used for pastas and pizzas
  • Easy to make - You literally rough chop the tomatoes & peppers in big chunks and stick it in the oven.
  • Packs CRAZY flavor for very little work!
  • Keeps well in the fridge and freezer
  • My family loves it!

Ingredients

Here is what you will need to make this sauce

You only need 3 main things - tomatoes, red bell peppers and some mixed herbs. Rest is all upto you!

Ingredients to make the roasted tomato and red pepper pasta sauce
Fresh tomaotes
Garlic
Onion
Red Peppers
Dried herbs

You can add onions or not. You can add oil or keep it oil free.You can add more veggies like carrots and turnips or not!

Tomatoes

Use any kinds of tomatoes you can find. Really. They should just be ripe.

Over the years I have used local Indian tomatoes, hybrid tomatoes, cherry tomatoes, beefsteak tomatoes and rainbow tomatoes! You name it and I have used it!

I wouldn't suggest roasting canned tomatoes. Instead, you can also use canned fire roasted tomatoes and skip the process of roasting the tomatoes in the oven.

Just cut the tomatoes roughly. Really, no need to finesse here. We will be blending them anyways.

Red Peppers

This is the other essential ingredient to make this recipe.

It does a few things to the sauce

  • Gives it body and heft
  • Gives it spice and sweetness
  • Also! gives it a beautiful red color.

Just halve the pepper. Keep the seeds if you wish or discard. I don't bother removing.

The peppers are always kept on the top so that the skin gets charred. It adds crazy flavor!

Onions

You can choose to omit it but i like the taste of onions in the sauce.

Use any kind you wish- white, yellow or red.

Onions burn faster than the rest of the ingredients and that is why they go to the bottom of the pan.

Garlic

I love the taste of roasted garlic. I can eat it with anything! I always add it to the sauce.

If you don't want the extra work and clean up, you can add garlic powder or garlic cloves at the bottom along with the onions.

Herbs

Use what you have. Have some pizza seasoning left over form yesterdays pizza? Use that.

Or use fresh herbs.

Fresh Basil is heavenly in this sauce. So if you have it or can get your hands on it, use that! Besides basil, you can add thyme, rosemary, oregano too.

1 part dried herbs = 3 parts fresh herbs

One tablespoon of dried herbs usually add as much flavor as 3 tablespoon of fresh herbs.

How to Make Roasted Red Pepper Tomato Sauce

This recipe will make about 1 quart of sauce. You can halve the recipe if you wish.

If you are cooking for a single person, you can divide the ingredients by 4 instead.

Though I am pretty sure once you make it, you will want to make as large a batch as possible. Because it's that good!

Step 1: Chop & Arrange

Slice the onions and add it to the baking sheet first. Onions get burnt very easily and that is why we will keep them at the bottom of the pan.

Now Roughly chop the tomatoes into four or 8 pieces based on the size. A rough random chop is all we need. Add them over the sliced onions.

Remove the green stem of the bell pepper using your thumb. Tear it into two halves or use a knife to cut it into big pieces.

Add the peppers on top of it all.

Garlic - Cut the top of the garlic. Drizzle oil if you please. Wrap it in the aluminum foil. Stick it in the middle.

Step 2: Season

You can add a drizzle of olive oil and salt to the tray before baking.

Or you can do it when you blend the sauce.

Step 3: Bake

Pop the whole tray into the oven.

Bake in the at 200 degrees C or 400 F for 60 minutes till the bell peppers are charred and black.

When the red peppers almost burn, the sauce is ready to be taken out of the oven.

Yes you read that right. BURN THEM PEPPERS!

Step 3: Remove Pepper Skins

Once you take the roasted vegetables out of the oven, let them cool a bit before you attempt anything else.

Remove the charred skin of the peppers. They will come right off. Again, dont bother being perfect here. Just do what you can.

Step 4: Blend

If you are impatient like me, put them in a bowl and using a hand blender, blend the sauce roughly.

Or if you are lazy like me, you can leave the sauce in the oven to cool down before you remove the skin and blend them in a blender.

Do not make the sauce too smooth. You want little chunks ,bits and bobs.

Add the dried herbs or chopped up fresh herbs.

Give it a grand mix and that's it! Your sauce is ready!!

Notes

Here are some important points that you need to know to make this

  • Exact ratio of tomatoes and peppers isn't very important. Though if you are making this sauce for the first time, use the measurements given in the recipe.
  • Dried herbs pack a heftier punch than fresh herbs.
  • You can add carrots , radishes and other vegetables to the roasting pan too. No one will know!
  • Remove the seeds of the red pepper to reduce the spiciness. But only if you are using spicy peppers.

Storing & Freezing

Listen to one thing..Just one thing I say..Make a giant batch of this..It keeps in the fridge for 5-7 days.Just make sure to use an air tight container to store it.

Better yet..Freeze it! Use a zip lock bag- plastic or silicon or large ice cube tray. It keeps well for 2-3 months.

Easy Pasta - Add a knob of butter, some sauce and the pasta water to a pan.Add cooked pasta. Top it with a generous amount of parmesan. And done! Add veggies or not.

Baked Sauce - Mix the sauce with el dente pasta in a casserole. Top with cheese and bread crumbs. Bake closed for 20 minutes at 180C. To brown the top, bake for 10 minutes at 200C.You can also make these three cheese stuffed shells using this homemade roasted tomato sauce.

    This is such an amazing find! I will be eternally thankful to Chhavi for saving me from buying the readymade bottled tomato sauces. Such an easy recipe where you just need to spend 5 minutes chopping vegetables, rest 1 hour baking and roasting job the oven does for you, and then just blend it for a few seconds. Brilliant and yummy!!! Definitely definitely highly recommended!
