Sometimes, the day just drags on, and all you want is something that feels like a warm hug on a plate. This one pot creamy penne Alfredo hits that note perfectly—rich, silky, and just the right amount of indulgent without the fuss.
Last week, I remember coming home after a day that was more chaotic than I expected. The kind where you almost forget to eat until the clock is glaring at you. I started this recipe while trying to keep an eye on a slightly distracted kiddo who was humming a tune but somehow managed to spill a little milk. It wasn’t perfect, but that’s the charm. The kitchen filled with the scent of garlic and butter mingling in a way that made the day’s stress melt away. A few stirs, some gentle simmering, and suddenly the creamy sauce and tender pasta were ready to rescue dinner. It felt like a little victory, even if the table wasn’t perfectly set.
Why You’ll Love It
- Comfort food with minimal cleanup since everything cooks in one pot—because who really wants to do dishes after a busy day?
- The creamy sauce develops right alongside the pasta, so you’re guaranteed a rich, velvety texture without needing to babysit multiple pans.
- It’s simple—and that’s kind of the point. No complicated steps, just straightforward, satisfying flavors.
- Customizable heat with just a hint of red pepper flakes, which you can easily dial back if you prefer it milder.
If you’re worried about the sauce being too heavy, I usually find it strikes a nice balance between indulgent and smooth, but I haven’t tested all variations with different milks. Still, it feels just right for a weeknight treat.

Ingredients
12 ounces penne pasta
4 cups whole milk
2 cups low sodium chicken broth
4 cloves garlic, minced
1 teaspoon salt
1/2 teaspoon black pepper
1/4 teaspoon crushed red pepper flakes
1/2 cup unsalted butter
1 cup freshly grated Parmesan cheese
2 tablespoons all-purpose flour
2 tablespoons chopped fresh parsley
Instructions
In a large deep skillet or wide pot, melt the butter over medium heat.
Add the minced garlic and sauté for about 1 minute until fragrant, stirring frequently to avoid burning.
Sprinkle the flour over the melted butter and garlic, whisking constantly to form a roux. Cook for 1-2 minutes until lightly golden.
Slowly pour in the whole milk and chicken broth while whisking continuously to prevent lumps.
Add salt, black pepper, and crushed red pepper flakes to the liquid mixture and stir well.
Bring the mixture to a gentle simmer over medium heat.
Add the penne pasta to the pot and stir to submerge it in the liquid.
Cook uncovered, stirring frequently, for about 12-15 minutes or until the pasta is tender and most of the liquid has been absorbed.
Reduce heat to low and stir in the grated Parmesan cheese until melted and the sauce is creamy.
Taste and adjust seasoning with additional salt and pepper if needed.
Remove from heat and sprinkle chopped fresh parsley over the top before serving.
Kitchen Notes
You’ll want a wide pot or a deep skillet with a lid handy for this one, nothing fancy—just something that can hold everything comfortably. I sometimes add a handful of fresh spinach at the end for a little green, which works surprisingly well. If you’re feeling adventurous, swapping Parmesan for Pecorino or adding a splash of white wine during the simmer can shake things up, but honestly, the classic version is tough to beat. Leftovers reheat nicely, though I usually add a splash of milk to bring back that creamy texture without drying out.
FAQ
Can I make this dairy-free? I haven’t tried it myself, but swapping in plant-based milk and vegan butter might work, just watch the sauce consistency.
What if I don’t have penne? Other pasta shapes like rigatoni or ziti should be fine; just keep an eye on cooking time.
Can this be made ahead? It’s best fresh, but leftovers stored in the fridge reheat well with a bit of extra milk.
