Gather the ingredients

The first thing you need to do to make this delicious pasta is to gather all of the ingredients. For starters, go to the produce section at the grocery store and grab three red peppers and a large white onion. Moving onto the aisle with canned goods, throw a 14.1-ounce can of chopped tomatoes into your cart. 

You will also need some Italian herbs for flavor and three cloves of garlic with the skin on. Let's be honest, is any recipe complete without garlic? We think not. Last but not least, add a tablespoon of flour. Now, we're ready to get started. 

Preheat the oven and prep the peppers

Since you need to cook the peppers in the oven, go ahead and preheat your oven to 410 F. That way, it will be nice and hot when you're ready to put the veggies in.

As you're waiting for the oven to preheat, grab the peppers and onions and roughly chop them. Then, place them on a baking sheet and drizzle with a little bit of olive oil. Sprinkle some Italian herbs on top, and then make sure that the oven has fully preheated before you put them in. Set the timer for 15 minutes.

Add the garlic

Once the first timer dings at 15 minutes, use oven mitts and pull out the baking sheet out of the oven. Add the whole garlic cloves with the skin and all onto the baking sheet with the onions and peppers. Then, slide the baking sheet back into the oven and set your timer for an additional 20 minutes. This will help the garlic get nice and mushy, so it's easy to work with. In the meantime, there's nothing else that you need to do for prep, so just kick back and relax. 

Remove the baking sheet and peel the garlic

When your second timer goes off, remove the baking sheet from the oven. Always remember safety first, and grab those oven mitts before you touch the baking sheet. Once it's cool enough to work with, grab each garlic clove and peel the skin off.

Then, transfer the veggies (including the garlic) to a blender, and add the can of chopped tomatoes. Swirl a little bit of water around the bottom of the can and add that to the blender as well. Blend the sauce until it comes out smooth.

Heat the sauce on the stove and serve

Once the sauce is smooth, transfer it to a pan and place it over heat on the stove. Heat through and then stir in the flour until everything is well combined. Brookes recommends serving this dish with cooked pasta and adding fresh herbs or Parmesan cheese on top. "It should work well with any kind of pasta — fusilli, spaghetti, penne, or even with filled ravioli," Brookes says. 

If you're making this for a crowd, we don't think you will have leftovers, but if you do, we have you covered. "Leftover sauce should keep well in the fridge for up to four days or in the freezer for up to three months," Brookes shares. Enjoy!
