Delicious Burnt Broccoli Pesto!

Hi, welcome back to YumsJunction! In this post, I am going to show you how to make a delicious burnt broccoli pesto. Yes, you heard that right, burnt. And honestly, it is so, so good.

We are starting with some fresh broccoli, a pestle and mortar, and a whole lot of flavor. I feel like “charred” is a more elegant way to put this, but we are actually straight up burning the broccoli, just not so much that it turns into ash, which also keeps it toddler‑friendly if you want to share.

Why You’ll Love This

The reason I absolutely love to char vegetables is that you get to have two completely different flavors out of one single ingredient. Part of the broccoli stays nice, fresh, and vibrant, while the charred side becomes pleasantly bitter, deep, and fragrant. It is amazing.

Plus, this is not just for pasta. Because it has a lot of good olive oil that helps preserve everything, this pesto will keep in the fridge for up to one week (and up to about two weeks if well covered in oil). You can pair it with sandwiches, stews, toast, eggs, or soft toddler pasta shapes, pretty much anything you can think of.

What You’ll Need

Special Equipment

• Heavy skillet or pot (to weigh down the broccoli)
• Mortar and pestle (highly recommended for texture control, though a food processor works)
• Large mixing bowl (for the final assembly)

The Ingredients

• 8 oz (225 g) broccoli florets (about 1 medium head)
• 4 to 5 tbsp good quality extra virgin olive oil, divided (plus more as needed)
• Splash of water
• Kosher salt, to taste
• 1 lb (450 g) rigatoni (or pasta of choice, you can use smaller shapes for toddlers)
• 1 tsp whole black peppercorns
• 1/4 cup pecans (or pine nuts, walnuts, or sunflower seeds)
• 3 standard cloves of garlic (or 8 to 10 very tiny ones)
• 1 handful fresh basil leaves
• 1/2 cup freshly grated Parmesan cheese, plus more for garnish

Let’s Get Cooking!

1. Let It Burn (Prep the Broccoli)

Start by trimming your broccoli florets. Get about 8 ounces of broccoli, which is essentially just one medium broccoli head. Get a pan on medium heat and drizzle in a couple of tablespoons of olive oil. Once your oil looks nice and hot, toss in the broccoli florets to get a nice little sizzle going.

You want the pieces in a single layer as much as possible so they char nicely.

2. The Char (Pro Tip!)

Now, we want to char it. We want to get that nice, beautiful burn. To do this, immediately weigh the broccoli down using another skillet, another pot, or whatever you have heavy on hand (I like using a tiny cast iron cookie skillet).

Pro tip: You do not want to move it, you do not want to toss it. You just want to let it burn, let it do its thing, and let it get nice and deeply charred on the bottom for about 3 to 4 minutes. For toddlers, make sure it is dark brown and crisp in spots, not completely black all the way through.

3. Steaming Things Up

Once you see that beautiful charred crust, remove the heavy weight and give the broccoli a little toss in the pan. Now we are going to go in with a splash of water to steam it. This will cook and soften the broccoli, which is exactly what we need in order to blend it.

Warning: Make sure you are not too close to the pan when you throw in the water. Things will steam and splash everywhere, and you do not want your face near that. Quickly cover it with a lid and give it about 7 to 10 minutes, checking occasionally, until it reaches a beautiful, bright green color and is tender but not total mush.

4. The Great Pasta Water Debate

While your broccoli is steaming away, prepare a pot of boiling hot water to cook the pasta in.

I always give this tip when it comes to pasta water. I know everyone is like, “Oh, it has to be as salty as the ocean.” It does not. You can always add more salt if needed, but you can not take it out. If you have already added enough salt to your pesto sauce, you do not want things to go crazy.

I usually just do two big, five finger pinches of salt. Do not get me wrong, I like salt, but I feel like we are a bit misled with the whole “ocean water” thing.

5. Boil the Pasta (Not Al Dente!)

I chose rigatoni for this post, but use whatever shape you want. Add the pasta and cook it all the way through. Keep in mind, we are making a pesto, so we do not want to cook the pasta al dente. It does not need further cooking or emulsifying on the stove later. For toddlers, you can choose a smaller shape and cook it an extra minute so it is very soft.

Reserve a tiny splash of pasta water before draining.

6. Mashing Up the Pesto (Mortar and Pestle Gang)

My absolute favorite tool to use for pesto is a mortar and pestle because I can control the texture. I like a rough texture when it comes to pesto, especially having the charred broccoli in there.

• Peppercorns: Start with the whole peppercorns and give them a rough crush. Do not use pre ground pepper, the scent of freshly crushed peppercorns does not compare to anything else. For toddlers, you can simply use a little less pepper overall or scoop their portion from a slightly milder part of the bowl.
• Pecans: Toss in a handful of raw pecans and crush. Make sure they are broken down into very small pieces with no big chunks, especially if you are serving toddlers.
• Garlic: Add the garlic cloves along with a pinch of salt. The salt acts as an abrasive agent that really helps crush the garlic. Mash well.
• Herbs and cheese: Toss in the fresh basil and another pinch of salt, then mash again. Mix in the grated Parmesan.

7. Add the Broccoli and Emulsify

Set aside a few nice charred broccoli florets for garnish later. Add the rest of the steamed or burnt broccoli to the mortar a few pieces at a time, roughly crushing them into the mixture.

Slowly stream in 2 to 3 tablespoons of good quality olive oil, mixing with a spoon, until the pesto reaches your desired, slightly chunky texture. Taste and adjust salt if needed (you can keep it more lightly salted if serving to toddlers and season adult portions at the table).

8. The “Grandma Bowl” Assembly

Whenever it comes to pesto pasta, you need a large mixing bowl to mix everything in. There is just something so satisfying about it. I feel like a grandma when holding the giant bowl, just mixing away.

Dump in the cooked pasta along with a teeny tiny splash of your reserved pasta water to loosen things up. Add a couple of large tablespoons of your broccoli pesto and toss vigorously to coat.

9. Serve

Top the pasta with the reserved charred broccoli pieces and a shower of extra Parmesan cheese. For toddlers, cut any large pasta pieces smaller and cool it slightly before serving. Enjoy.

A vibrant, beautifully charred, and pleasantly bitter broccoli pesto tossed with rigatoni. Made with fresh basil, pecans, and garlic, this rustic take on pesto is packed with deep, complex flavors, and can be made toddler‑friendly by keeping the char gentle and the nuts finely crushed.

Ingredients

• Equipment Needed

• Heavy skillet or pot (to weigh down the broccoli)

• Mortar and pestle (highly recommended for texture control, though a food processor works)

• Large mixing bowl (for the final assembly)

• Full Ingredients List

• 8 oz (225 g) broccoli florets

• 4 to 5 tbsp extra virgin olive oil, divided (plus more to taste)

• Splash of water

• Kosher salt, to taste (use a light hand if serving toddlers)

• 1 lb (450 g) rigatoni pasta (or smaller shapes for toddlers)

• 1 tsp whole black peppercorns

• 1/4 cup (30 g) pecans

• 3 cloves garlic

• 1 handful fresh basil leaves

• 1/2 cup (45 g) freshly grated Parmesan cheese

Directions

• Heat about 2 tbsp olive oil in a pan over medium heat. Add broccoli florets in a single layer, weigh them down with a heavy skillet, and let them char undisturbed for 3 to 4 minutes until the bottoms are deeply browned.
• Toss the broccoli, carefully add a splash of water, and immediately cover with a lid. Steam for 7 to 10 minutes until tender and bright green, not mushy.
• Boil a pot of water, season with a moderate amount of salt, and cook the rigatoni completely through. Reserve a splash of pasta water, then drain.
• In a mortar and pestle, roughly crush the peppercorns. Add pecans and crush until there are no large chunks left. Add garlic and a pinch of salt, mashing into a paste. Crush in the basil, then stir in the Parmesan.
• Reserve a few charred broccoli florets for garnish. Add the remaining broccoli to the mortar in batches, roughly crushing them.
• Stream in 2 to 3 tbsp olive oil (or more as needed) and stir until you reach a chunky pesto consistency. Taste and lightly adjust salt.
• In a large bowl, toss the cooked pasta, a tiny splash of pasta water, and the pesto together until everything is coated.
• Garnish with the reserved charred broccoli and extra Parmesan. Cut pasta smaller and let it cool slightly before serving to toddlers.

Notes

• Storage
  Keep leftover pesto in a jar in the fridge for up to 1 week (and up to about 2 weeks if very cold and well covered with olive oil).
• Swaps
  If you have a nut allergy, swap the pecans for sunflower seeds or simply leave them out. Any pasta shape works, but rigatoni, spaghetti, or smaller shapes for toddlers are fantastic.
• Pro Tips
  Do not use pre ground pepper; whole crushed peppercorns make a world of difference. Also, make sure to cook your pasta fully, since pesto does not get cooked in a pan with the pasta, al dente noodles will be too tough, especially for toddlers.
