So Easy, So Comforting!
I’m especially excited to share this Gluten-Free Spaghetti Aglio e Olio recipe with you. When I think back to the very first Italian recipe I ever made completely on my own – once I was finally allowed to use the stove – it was this one. At the time, I had no idea it even had a name. I just knew I loved the smell of garlic sizzling in olive oil and how comforting it tasted tossed with pasta.
Even back then, I always added crushed red pepper flakes, not realizing that was actually the traditional way to make it. And while it’s not technically classic, I’ve always loved finishing it with a big mountain of freshly grated cheese.
This pasta with olive oil and garlic has been my comfort food for as long as I can remember, and the good news is – it’s incredibly easy to make gluten free. The key is choosing the right gluten-free pasta, which I’ll walk you through below. And if you’re not gluten free, you can use this exact recipe with regular spaghetti and it will still be perfect.
I’ve made this dish hundreds of times over the years, and along the way I’ve learned a few small techniques that make a big difference – especially when it comes to cooking the garlic. I typically love minced garlic, but for this recipe, thinly sliced garlic is the way to go. It turns golden, lightly caramelized, and almost chip-like in the oil – absolutely delicious.
I also add the garlic to the olive oil while it’s still cool and bring everything up to heat together. This gives you much more control and prevents burning. And while some recipes suggest cooking the pasta and garlic at the same time, I prefer to cook the pasta first. The garlic cooks quickly, and there’s no need to add extra stress to your life.

Ingredients
Below is a breakdown of the ingredients you’ll need for gluten-free spaghetti aglio e olio, along with tips I’ve learned from making this recipe countless times.
Gluten-Free Spaghetti. The most important swap in this recipe is the pasta. After testing many brands, my top two recommendations are Rummo Gluten-Free Spaghetti and Jovial Gluten-Free Spaghetti. Rummo is my current favorite – it cooks beautifully, doesn’t break when tossed, and has an incredibly authentic texture. Jovial is a close second and has been a long-time staple in my kitchen. I’ve found both at Wegmans, so check your local grocery store. If you’re unsure which noodles to use, check out my guide to the best gluten-free pasta brands.
Reserved Pasta Cooking Water. Always reserve pasta water when cooking gluten-free pasta. Even if you don’t end up using it, having it on hand is key. A splash helps loosen the pasta, create a silky texture, and helps the olive oil coat the spaghetti evenly.
Extra-Virgin Olive Oil. Use the best-quality olive oil you can comfortably afford. I usually stick to a good mid-range option for cooking – Wegmans Organic or Aldi Simply Nature are both great choices.
Fresh Garlic. Garlic is the star of this dish. I usually “measure with my heart,” but for this recipe, 6–8 cloves of medium garlic is the sweet spot. Thinly slicing the garlic (instead of mincing) allows it to gently brown and caramelize in the oil, creating incredible flavor without bitterness.
Crushed Red Pepper Flakes. This adds just enough heat to balance the richness of the olive oil. Start small and adjust to your taste.
Freshly Grated Parmesan Cheese. Not traditional – but highly recommended. It adds richness and takes the comfort factor up a notch. Totally optional, but worth it.
Step-by-Step: How to Make Gluten-Free Spaghetti Aglio e Olio
Step 1: Prep everything first. Before you turn on the stove, slice the garlic and add it to the olive oil in a small bowl. Place in the fridge while the pasta cooks. Having the garlic ready – and already sitting in the oil – starts to infuse the garlicky flavor.
Step 2: Cook the pasta. Bring a large pot of well-salted water to a rolling boil. Add the gluten-free spaghetti and cook according to package directions until just al dente. Reserve ½ cups of pasta water, then drain and set the pasta aside.
Step 3: Start the garlic in cool oil. Place the sliced garlic and olive oil together in a large skillet or use the same pot used to cook the pasta. Set the heat to medium-low and warm the oil slowly, stirring occasionally, until the garlic becomes fragrant and lightly golden – about 1–2 minutes. Starting the garlic in cool oil gives you better control and prevents burning.
Step 4 Bloom the red pepper flakes. Add the crushed red pepper flakes to the skillet and continue cooking until the garlic is lightly golden and fragrant, about 1 minute. Adding the red pepper flakes directly to the warm oil helps bloom the spice and deepen the flavor. Be careful not to let the garlic burn.
Step 4: Add the pasta. Remove from the heat and add the cooked spaghetti directly to the skillet and toss gently to coat in the garlic oil.
Step 5: Adjust with pasta water (if needed). Add reserved pasta water a little at a time only if needed, tossing until the pasta is glossy and evenly coated. Not all pasta brands need it, so add just enough to loosen the sauce.
Step 6: Finish with cheese. Divide the pasta between plates, and finish with a generous helping of freshly grated cheese before serving.
Tried-and-True Expert Tips
- For deeper garlic flavor: If you know you’re making this recipe ahead of time, slice the garlic and let it sit in the olive oil for 15–30 minutes before cooking (keep in the fridge for safety). You can even do this a few days in advance and keep it in the fridge. The longer the garlic sits, the more flavor it infuses into the oil. The oil will solidify in the fridge, but don’t worry – it melts right back down as soon as it hits the pan. This is one of my favorite ways to really boost the garlic flavor without adding more cloves.
- Always start garlic in cool oil: This is one of the biggest mistakes I see with garlic-based pasta recipes. Heating the oil first and then adding the garlic makes it very easy to burn – and burnt garlic will ruin the entire dish. Starting the garlic in cool olive oil and slowly bringing it up to temperature gives you complete control and lets the garlic turn lightly golden instead of bitter.
- Cook gluten-free pasta fully: Because this dish doesn’t have a heavy sauce, the pasta won’t continue cooking once it’s added to the pan. If the pasta is undercooked when you drain it, it will stay that way. I recommend cooking gluten-free spaghetti until it’s just done with a slight bite, but still fully tender and enjoyable to eat.
- Use pasta water only if needed: Reserved pasta water is your safety net here. You may not need it at all, but if the pasta looks dry or isn’t coating evenly in the olive oil and garlic, add a splash at a time. It helps create a silky finish and brings everything together – especially with gluten-free pasta, which can dry out more quickly.
Serving Suggestions
This gluten-free spaghetti with olive oil and garlic is perfect on its own with extra cheese, but it also pairs beautifully with grilled shrimp, chicken, or Italian roasted vegetables. Serve it alongside a gluten-free Caesar salad or gluten-free garlic bread for a complete Italian-style meal.
Storing & Reheating Leftover Gluten-free Spaghetti with Olive oil and Garlic
This dish is best enjoyed fresh. If needed, store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stovetop or in the microwave with a splash of olive oil or water to help revive the pasta.
