The 15-minute pesto chicken with cauliflower rice turned my dinner game around when I was cutting back on carbs but got tired of eating boring salads. This super quick meal has become what I turn to when I'm short on time but don't want to be hungry again soon after eating. And let's be real, it's mostly just a way to enjoy cheese and pesto, which makes any veggie taste better.
When I first tried making cauliflower rice years back, I was totally doubtful. My early attempts were pretty terrible - soggy, flavorless mush that had me reaching for my phone to order takeout. Then I learned you need to treat cauliflower rice as its own thing, not just a sad rice replacement. Now this pesto version gets requested even by friends who love their carbs.
Ingredients You'll Want
- Cauliflower rice - grab it pre-made to save time, or make your own to save money
- Already-cooked chicken - grabbing a rotisserie chicken is my favorite shortcut
- Red pesto - honestly, the stuff from a jar works perfectly
- A couple tomatoes - whatever doesn't look too sad at the store
- Garlic - go for the fresh stuff, not the jarred kind if possible
- Mozzarella cheese - the bagged shredded type is totally fine
- Some arugula - gives everything a nice peppery taste
- Fresh dill - skip it if you want, but it adds something special
- A bit of milk - creates creaminess without heaviness
- Olive oil, salt, pepper - your basic cooking must-haves

Cooking Steps
Prep Work FirstI always start by getting all the cutting done - chopping the tomato, mincing the garlic, cutting up the dill if I'm using it, and pulling apart the chicken. Takes about 5 minutes but makes cooking go way faster. Using pre-riced cauliflower puts me ahead from the start.
Begin CookingI pour a bit of olive oil in my pan, toss in the tomatoes and let them soften for a minute or two. Then I add the cauliflower rice and about half the garlic. I only stir it around long enough to warm everything and release the garlic smell - around a minute. If you cook cauliflower rice too long, it turns into sad mush.
Mix In Main IngredientsAfter that, I put in the chicken, a generous dollop of pesto, and some salt. Sometimes I throw in a bit of tomato paste if it's handy. A quick stir, then I cover the pan for about 2 minutes. This warms everything through and lets the flavors start to blend together.
Add CreaminessNow comes my favorite part - I pour in a little milk and sprinkle half the cheese on top. After putting the lid back on for 2-3 minutes, the cheese gets all melty and the milk turns into a light sauce that coats everything. It's not heavy like using cream would be, but adds just enough richness.
Final TouchesAt the very end, I toss in the rest of the cheese, the remaining garlic (fresh garlic gives it a nice kick), the arugula, and dill. The heat that's left wilts the greens just right, and I take the pan off the heat before the herbs lose their freshness.
I came up with this dish during a hectic work week when I was living on coffee and granola bars until dinner time. I had cauliflower that was about to go bad, some leftover rotisserie chicken, and pesto in the fridge. The first try turned out so tasty that I actually looked forward to eating the leftovers, which doesn't happen often with my kitchen experiments.
Ways To Enjoy It
I usually end up eating this straight from the pan because I'm starving by the time it's ready. If I want to fancy it up, I'll add some red pepper flakes on top. For my husband who runs marathons and needs extra carbs, I serve his portion with a bit of actual rice underneath or some crusty bread on the side.
Tasty Variations
When I'm out of chicken, I've swapped in a can of white beans for a meat-free option. Shrimp works great too and cooks even faster. You can use green basil pesto instead of red, but you might want to add some red pepper flakes to make up for the flavor. Sometimes I just throw in whatever veggies are about to go bad in my fridge - bell peppers, zucchini, or even some frozen peas work well.

Honest Truth
- You can totally use those bags of pre-riced cauliflower. They cost more but save time and cleanup
- If cauliflower isn't your thing, this probably won't be the dish that changes your mind
- The cheese is non-negotiable - it's what makes this feel like a real meal instead of a diet food
What I love most about this dish is how it hits the spot when I'm craving pasta but don't want to feel sluggish afterward. It's become my go-to Wednesday dinner when I can't face cooking but takeout seems too expensive. My neighbor asked me for the recipe after I brought her some when she wasn't feeling well, and now she makes it for her kids by hiding the cauliflower under lots of cheese. Hey, whatever gets veggies on the table!
Frequently Asked Questions
- → Can frozen cauliflower rice be used?
- Yes, frozen works great! Use it straight from the bag, no defrosting needed, but you might need an extra minute or two in the pan.
- → What is red pesto, and any swaps?
- Red pesto uses sun-dried tomatoes instead of basil. If unavailable, green pesto with some tomato paste or just sun-dried tomato paste will work.
- → What if I want a dairy-free version?
- Swap the milk for coconut milk or stock, and either skip the cheese or go for a dairy-free option. It’ll be less creamy but still taste great.
- → Is it good for meal prep?
- Yes, you can store it for 2-3 days in airtight containers. Reheat with a splash of broth or water in a pan or microwave to keep it fresh.
- → What’s a good arugula substitute?
- Baby spinach, kale, or mixed greens will do the trick. Kale takes a little more time to soften, so add it earlier than other greens.
- → Is this dish okay for keto diets?
- Absolutely. It’s low-carb, only 19g per serving, with carbs mainly from veggies, so it fits most keto guidelines.
