I get it, I really do! It feels like just yesterday I was drowning in that exact chaos, juggling a demanding job and family life.

Effortless 5-Ingredient Pesto Rigatoni Recipe
Okay, now for the star of the show! This 5-Ingredient Pesto Rigatoni is the recipe that totally proves you don’t need a ton of stuff to make something amazing. It checks all the boxes for those crazy weeknights: ridiculously fast, super simple, and totally delicious. Seriously, it’s a guaranteed winner for your 5-Ingredient Dinner Ideas (No Fail) list!
Ingredients for Your 5-Ingredient Dinner Ideas (No Fail)
Here’s what you’ll need to round up. It’s such a short list, you’ll be amazed!
- 1 lb Delallo Rigatoni
- 6.35 ounces Delallo Simply Pesto (that’s 1 jar!)
- 1 cup Delallo Crushed Tomatoes
- 1/4 cup reserved pasta water (you might not use all of it, that’s okay!)
- 2 cups shredded mozzarella cheese
- Fresh basil, chopped, for garnish (This is our “bonus” ingredient, but it makes it pop!)
Simple Steps for 5-Ingredient Pesto Rigatoni
- First things first, crank up that oven to 400°F (200°C). Get it nice and hot!
- Meanwhile, get a big pot of salted water boiling for your pasta. Don’t skimp on the salt; it makes a difference!
- Toss in your rigatoni and cook it until it’s perfectly al dente – you know, tender with just a little bite to it.
- Before you drain everything, scoop out about a quarter cup of that starchy pasta water. This is liquid gold for making our sauce creamy!
- Drain the pasta and then dump it right back into the warm pot. Add in the pesto and crushed tomatoes. Start with a little of the reserved pasta water, just enough to make it nice and saucy, and stir it all together. You want it coated, not swimming!
- Give a 9×13 inch baking dish a quick spray with nonstick cooking spray so nothing sticks.
- Now, spread about half of that glorious pasta mixture into the dish. Sprinkle half of your mozzarella cheese over the top. Then, do it all again – the rest of the pasta, and the rest of the cheese.
- Pop that into your preheated oven for about 20 minutes. You’re looking for that cheese to be all melted and bubbly and looking super inviting.
- Once it’s out and looking amazing, give it a sprinkle of that fresh chopped basil. It just adds that perfect fresh finish!
Tips for Success with 5-Ingredient Dinner Ideas
Want to make sure this comes out perfectly every single time? Here are a few little tricks I’ve picked up:
- Pasta Water is Key: Don’t skip reserving that pasta water! It helps emulsify the sauce, making it extra creamy and helping everything cling to the pasta beautifully. You’ll notice how it just marries the pesto and tomatoes together.
- Don’t Overcook the Pasta: Since it’s going back into the oven for a bit, cook your rigatoni just shy of al dente. It’ll finish cooking in the dish and won’t get mushy. We want that perfect bite, remember?
- Sauce Consistency Check: When you’re mixing the pasta, pesto and tomatoes, add the pasta water a tablespoon at a time. You’re aiming for a glossy, well-coated pasta, not a soupy mess. Trust your instincts here!
Ingredient Notes and Substitutions
So, about these ingredients! While the packaged pesto and crushed tomatoes are total lifesavers for this 5-Ingredient Dinner Ideas (No Fail) recipe, don’t be afraid to play around if you have other things lurking in your pantry!
If you’re not a fan of jarred pesto, you can totally use your favorite homemade version if you have some handy. Or, maybe a basil-heavy store-bought one will work just as well! For the tomatoes, any good quality crushed tomatoes will do the trick. And for the pasta? Rigatoni is awesome because it holds sauce so well, but penne, rotini, or even farfalle would be super delicious here too. It’s all about what you’ve got and what you like!
Equipment Needed for Your 5-Ingredient Dinner Ideas
You really don’t need much special gear for this quick meal. It’s all about keeping things simple!
- A big pot for boiling your pasta.
- A baking dish (a 9×13 inch one works perfectly for this).
- A colander for draining the pasta – easy peasy!
- A stirring spoon or spatula to mix everything together.
Serving and Storage for 5-Ingredient Pesto Rigatoni
Serving this cheesy, saucy rigatoni is almost as easy as making it! That sprinkle of fresh basil on top? It’s not just for looks, it adds this amazing fresh pop of flavor that really brightens everything up. It’s perfect straight from the oven while that mozzarella is still melty and gooey. If you happen to have any leftovers (which is rare in my house!), just pop them into an airtight container in the fridge. They’ll keep for about 3 days. To reheat, I like to give it a little splash of water or milk and microwave it gently until it’s warmed through. Sometimes, I even pop it back under the broiler for a minute to get that cheesy topping bubbly again!
Frequently Asked Questions About 5-Ingredient Dinner Ideas (No Fail)
Got questions about whipping up these super simple dinners? I’ve got answers! These are all about making your life easier with delicious, budget-friendly meals.
Can I make the Pesto Rigatoni vegetarian?
Absolutely! This recipe is already fantastic as is for vegetarians. The Delallo Pesto, crushed tomatoes, pasta, and mozzarella are all vegetarian-friendly. If you wanted to add some extra veggies for more bulk, that would be awesome too for these family meals!
What other vegetables can I add to the Pesto Rigatoni?
Oh, let’s get creative! Since this is a 5-Ingredient Dinner Ideas (No Fail) recipe, we’re keeping it simple, but if you have some other goodies on hand, toss them in! Some spinach wilted in at the end with the pasta would be divine, or some chopped zucchini or bell peppers sautéed before adding them to the dish would be yummy. Just remember, we’re aiming for easy weeknight dinners, so don’t go overboard with prep!
How long does it actually take to cook the pasta?
For rigatoni, it usually takes about 10-12 minutes to get it perfectly al dente. But always check the package directions because it can vary a little between brands! Remember, we want it just shy of done since it’ll finish cooking in the oven.
Can I use a different type of pesto?
You sure can! The Delallo Simply Pesto is super convenient, but if you have your favorite store-bought pesto or even a homemade batch in the fridge, go for it! Any good quality basil pesto will work beautifully and still keep these easy weeknight dinners a breeze.

Precision Keto Scientist
Numbers don’t lie, and neither do my recipes. I’m a biochemist who fell into keto cooking through my own metabolic research—and I approach recipe development like a lab experiment, complete with macro calculations precise to the tenth of a gram.
My journey started in diabetes research labs at Johns Hopkins, where I spent six years studying how different macronutrient ratios affected insulin sensitivity. Personal experimentation with therapeutic ketosis for cognitive enhancement led me down a rabbit hole of recipe testing that eventually consumed more hours than my actual day job.
While other cookbook authors describe flavors and textures, I quantify ketone elevation curves and glycemic impact data. My recipe database contains 340+ formulations, each tagged with detailed nutritional analysis, predicted ketosis timing, and optimal meal spacing. I measure salt by weight, time cooking processes to the minute, and log ingredient sourcing obsessively for consistent results.
My breakthrough research on fat-protein ratios for sustained ketosis got published in the Journal of Nutritional Biochemistry. My “Macro Math Mastery” workshops have trained over 5,000 people in precision meal planning. I even collaborated with continuous glucose monitor manufacturers to create the first real-time feedback system for recipe optimization.
I left my pharmaceutical research position at Merck three years ago to focus on metabolic nutrition consulting. Now I work with professional athletes, biohackers, and medical professionals seeking therapeutic ketosis protocols. When I’m not in my lab-kitchen, I’m competing in chess tournaments or documenting my daily biomarker measurements with true data scientist obsessiveness.
Cooking is just applied chemistry—and chemistry follows predictable rules. Master the variables, control the outcomes.
