The Complete Shopping Rundown
Start with dry rigatoni or whatever pasta shape you like around 200-250 grams. Rigatoni holds sauce real good because of its ridges. Grab a 5.2 ounce pack of Boursin Fine Herbs & Garlic cheese. This stuff gives that creamy, herby punch you know and love.
Next, you need a lemon for zest and some juice to brighten things up. Don 27t forget one tablespoon of lemon juice because it kinda ties the flavors together. Chili flakes and ground pepper add that little kick. You only need about a quarter teaspoon each to gently wake up your taste buds.

Frozen peas bring in a sweet pop and some green color that makes the dish look alive. Parmesan cheese for sprinkling on top? Absolutely, around ¾ cup shredded. Finally, salt and pepper to finish your dish just right.
The Full Pressure Cooker Journey
First, preheat your oven to 375 degrees Fahrenheit, 190 if you think Celsius. This dish needs some oven love too. Grab your large ovenproof pot or Dutch oven that can go right from stove to oven.
Now toss in the dry rigatoni along with frozen peas and that package of Boursin cheese. Add lemon zest, lemon juice, chili flakes, and ground pepper. Pour in just enough water to barely cover the pasta; don 27t drown it. Stir it all up so everything gets mixed real good.
Cover the pot tight and pop it into the oven. Let it bake for 15 minutes. You 27ll see steam cues rising and that sealing ring doing its job keeping flavors locked in. After 15 minutes, take out the pot, and give everything a good stir.
Time to get cheesy! Sprinkle the shredded parmesan over the top and bake it again, uncovered this time, for another 5 minutes. This melts the cheese and makes the pasta tender just right, that tender pull you want without mush.
When it 27s done, carefully remove from oven. Stir gently and taste test, adding salt and pepper to your liking. That 27s the final step before plating.

Garnish with more lemon zest, chili flakes, and a little parmesan for a pretty finish. You 27re right there, ready to scoff down this creamy, herb-packed pasta masterpiece.
Quick Tricks That Save Your Time
- Use pre-zested lemon if you got it; it cuts out prep and gets you to dinner faster.
- Frozen peas work better than fresh here cause they steam perfectly in the pot without extra fuss.
- Measure water with a proper kitchen scale or cup so you hit broth depth without guesswork and no soggy pasta.
The Flavor Experience Waiting for You
From the first bite, you get that creamy richness from Boursin cheese hugging every noodle. It tastes kinda like a warm hug on a chilly day, simple and real good.
Then the lemon zest punches in with freshness, cutting down any heaviness and brightening the whole plate like sunshine.
The chili flakes are subtle but there, giving a quiet heat that lingers and keeps you interested till the last forkful.
And don 27t forget the parmesan on top, melting down to add more creaminess and that nutty, salty snap that makes the dish feel complete.
How to Store This for Later
Cool your pasta down a bit before putting in an airtight container. It keeps flavor locked and stops it from drying out. You can keep it in the fridge safely for about 3-4 days.
If you wanna freeze some, portion it out into sealed containers. When thawing, leave it overnight in the fridge and reheat gently on stove or microwave adding a splash of water or broth to bring back creaminess.
Leftovers reheat best on low heat 2Dstir often so it doesn 27t stick. That tender pull might soften more with storage but the flavors stay strong, so you 27re still in for a treat.
The FAQ Section You Actually Need
- Can I use other pasta shapes? Yeah totally! Just remember to adjust water a bit, cause size and shape soak different.
- What if I don 27t got Boursin? Cream cheese with herbs mixed in works but try to keep it flavorful.
- Can I skip the oven step and just pressure cook? The oven melt adds texture and bubbly cheese you don 27t wanna miss.
- How do I know when pasta 27s cooked perfectly? Watch the steam cues and do a quick tender pull test before finishing the bake.
- What 27s the sealing ring for? It locks in steam and pressure so your pasta gets cooked evenly and the sauce stays rich.
- Is this good for meal prep? Totally yes! Just store it right, it reheats well and tastes great next days.
