Prawn & Harissa Spaghetti

January 23, 2025

Prawn and harissa spaghetti is a bold, vibrant dish that brings heat, richness, and freshness together in a single bowl. With tender prawns, spicy harissa, and perfectly cooked spaghetti, this recipe takes a simple pasta dinner to a whole new level. It’s fast enough for a weeknight yet exciting enough to serve for a special occasion when you want to impress without spending hours in the kitchen.

What sets this dish apart is the harissa paste – a North African chili blend made with roasted peppers, garlic, and spices. It delivers a smoky heat that pairs beautifully with the sweetness of the prawns. Just a spoonful adds depth and fire, giving the sauce a complex flavor that lingers in the best way.

The base of the dish starts with olive oil, garlic, and maybe a pinch of red pepper flakes if you’re a fan of extra spice. Once the garlic is fragrant, the harissa paste is stirred in, followed by a splash of pasta water or white wine to loosen the sauce and bring everything together. The prawns go in next, cooking quickly until they turn pink and tender, soaking up all the spicy, garlicky flavor.

Cooked spaghetti is tossed straight into the pan, where it’s coated in the fiery sauce and mixed with the prawns. A handful of fresh herbs like parsley or cilantro adds brightness, while a squeeze of lemon over the top lifts the whole dish and balances the heat.

You can easily customize the dish by adding cherry tomatoes, wilted greens, or crumbled feta for a creamy contrast. It’s a flexible recipe that invites creativity while still delivering a big payoff in flavor.

Prawn and harissa spaghetti is a pasta dish with personality – bold, spicy, and totally addictive. It’s a refreshing departure from the usual marinara or Alfredo and a delicious way to bring global flavor to your dinner table. Serve it with a glass of chilled white wine and crusty bread for a meal that feels both relaxed and refined.

    Meh, didn’t impress me. I thought spaghetti was supposed to be with tomato sauce or something. Harissa just kinda weird.

    I don’t really know about using harissa. Isn’t it a bit strong for pasta? My kids wouldn’t eat it…

      I get what you’re saying! Harissa can be strong, but you can always use less. Just adjust it for your kids’ taste! They might surprise you!

      Harissa? That stuff is spicey! I would not feed that to my kids, they prefer plain spaghetti! Sounds fun tho!

    Really good dish! I added some extra garlic and it made it even better. The prawns were cooked perfectly.

    I think 2 minutes with spaghetti might be too long depending on how saucy your pan is. Mine dried out a bit. Add oil/pasta water maybe.

    This recipe was amazing! The harissa gave it such a great kick. Will definitely make again!

    I made this exactly as written and it’s seriously spicy in the best way. The lemon at the end really balances the harissa. Would make again for sure.

    This was a total hit! My family loved it. ❤️

    The garlic step is key. I rushed it and the garlic got a little too brown, so my whole batch tasted bitter. Lesson learned.

  11. 5 stars
    Soo easy! Just a couple ingredients and you got a fancy meal! 💖

    Tasty dish! The garlic and lemon combo was delish. I’m gonna try it with shrimp next time 😋

      Hmm, shrimp? This was okey but not sure how it’ll be with shrimp. Garlic and lemon is nice tho.

    Quick and easy – perfect for a weeknight meal! Not too much prep time. Thanks!

    Not a fan. The harissa was way too spicy for me. I added more lemon to tone it down but still…

  15. User avatar marty.kertzmann says:

    Pretty good but I thought 2 tbsp harissa was a lot. Next time I’ll start with 1 tbsp and adjust—my kitchen was on fire (emotionally and physically).

    1. User avatar Gerard Graham says:

      5 stars
      Totally get that—harissa can be *strong*. Starting with 1 tbsp and adjusting is the way to go. 😅 Glad you didn’t actually burn the kitchen down!

  16. User avatar bart.blanda92 says:

    I was nervous about the amount of harissa, but “adjust to taste” saved me. Next time I’ll add a splash of pasta water for extra sauce-y vibes.

  17. 5 stars
    Yum! So flavorful! I added some bell peppers and it was delish! 🍝

    Tried it, but my prawns didn’t turn pink. Are they supposed to? Not sure if I did something wrong.

  19. 4 stars
    My girlfriend loved it! I ain’t much of a cook, but followed the steps and it turned out great. Can I make it with chicken?

  20. User avatar elliot.gusikowski says:

    5 stars
    Yum!!!

  21. 5 stars
    Spicy, garlicky, and surprisingly fast. The harissa really clings to the prawns—mine turned out great after I cooked them just until pink.

  22. User avatar tyrell.marks58 says:

    For me it needed more salt—0.5 tsp felt low with the harissa. I’ll definitely taste as I go next time.

    What is harissa? Can you use something else? I’m not a fan of spicy food.

    1. User avatar sherita.smith51 says:

      Harissa is like a spicy paste made from chili peppers and spices. If you don’t like spice, you can try using a mild tomato sauce or just some olive oil and garlic! It’ll still taste good.

    2. User avatar kenyetta.lowe66 says:

      I dunno, never heard of harissa… can’t you just skip it? Who needs spicy stuff anyway? Can you use ketchup or something instead?

  24. User avatar alejandro.kulas says:

    Not gonna lie, I used pre-cooked shrimp (because I’m lazy) and it turned out weird and mushy. I think cook time matters a lot here.

  25. User avatar Imelda Walter V says:

    My family loved it, but I think the garlic was too strong. Next time I’ll use less.

    1. User avatar phil.padberg says:

      4 stars
      I think garlic is the best part! But I get it, it’s strong! Maybe try to roast it first? That makes it milder.

  26. 3 stars
    This was alright, but I think it could’ve used more flavor. Maybe some cheese or something.

    1. User avatar clarence.russel1963 says:

      4 stars
      I totally agree! It needed a kick, maybe some parmesan on top would help? 🧀

  27. 2 stars
    Honestly, the prawns were kinda rubbery. I’ll try it again but maybe adjust the cook time.

  28. 4 stars
    Super easy to make! My kids even liked it. Although I used shrimp instead of prawns.

    1. User avatar avery.hermann15 says:

      5 stars
      That’s awesome! Kids can be picky eaters, but it sounds like you found a winner. 🥇 What kind of shrimp did you use?

    2. 2 stars
      I dunno, shrimp instead of prawns? Isn’t that basically the same? Seems like a small change but okay.

  29. 5 stars
    YUM! Super easy to make and perfect for a quick dinner!

    1. 5 stars
      Glad you enjoyed it! It’s one of my go-tos for busy nights.

    This is such a punchy weeknight meal. The harissa + lemon combo is 🔥—mine turned out beautifully spicy, and the garlic aroma filled the kitchen.

  31. 3 stars
    Harissa paste is so strong—mine was almost too much. I adjusted to taste like it says, but I still felt like it took over everything. Not bad though.

  32. User avatar MAGA2024.Trumpster says:

    Yum! I love prawns! I added some cherry tomatoes and it upped the flavor! This recipe is a keeper.

    I’m not usually a harissa person, but I tried it anyway. The prawns were tender and the sauce clung nicely to the spaghetti. Might add a splash more lemon next time.

    Spaghetti with prawns? Sounds weird but it actually works. Good recipe!

  35. User avatar Anju's Mother says:

    Boring. Too simple. Needs cheese or something or more sauce. Otherwise just spaghetti with spicy oil.

    1. User avatar asa.bailey2026 says:

      4 stars
      I get what you mean—it’s pretty straightforward. But the harissa + lemon combo does bring a lot of flavor if you use a good paste. I wouldn’t call it just “spaghetti with spicy oil.”

  36. User avatar mauro.dooley1975 says:

    5 stars, all the way! The kids didn’t like it much but I thought it was great.

    1. User avatar tonita.runolfsson63 says:

      3 stars
      Sounds good, but my kids wouldn’t touch that harissa stuff. Is it too spicy?

    2. User avatar bradley.beier47 says:

      5 stars
      I can totally relate! My kids are picky eaters too. But hey, more for us, right? 😂

    This is one of those recipes that sounds fancy but is actually quick. Garlic fragrant, prawns pink, done. Loved it.

    Pretty simple to make but I feel like something’s missing. It was just…okay.

    1. User avatar w00d_ch0p says:

      I thought it was yum! Maybe try adding some cream next time? Just a thought!

    2. User avatar mathWizard says:

      I totally get you! It feels like a pinch of something like more spices or herbs could elevate it. Did you try adding some chili flakes?

    Absolutely loved this recipe! The harissa gave it a nice kick. Will definitely make again!

    1. 5 stars
      Thanks for sharing! I can’t wait to try adding harissa to my spaghetti. Sounds delicious!

      Loved it too, but my kids thought it was too spicy! Would recommend maybe using less harissa for family cooking.

  40. 3 stars
    Too much lemon for my taste. I think I’ll skip it next time.

    1. 5 stars
      I loved it! The lemon adds such a fresh zing. Maybe try less but don’t skip it completely!
