Do you have a favorite chip flavor? When I was a kid my absolute favorite was sour cream and onion. Weird, I know. Everyone else around me was obsessed with barbecue or Doritos but for me it was sour cream and onion all the way. Funny thing is, I haven’t had a sour cream and onion chip in a while. That is, until Mike and I were watching this YouTube show that we love. They did a giant snack bracket competition and the winning snack was sour cream and onion chips!

We had a little conversation about it and somehow Mike came up with the awesome idea of sour cream and onion pasta. What’s funny is that Mike doesn’t even like sour cream and onion. He’s never bought a bag and the most he’s ever had is a chip or two. He’s definitely missing out because sour cream and onion is a perfect combination. After trying this pasta he’s a convert!

What is sour cream and onion pasta?

Essentially I took all the flavors of sour cream and onion chips and put it into a pasta sauce. Sour cream and onion flavor is literally sour cream and onions so I basically made a bechamel (white sauce) with sour cream and chives stirred in. I had a little mental debate on whether the “onion” in sour cream and onion were onions, green onions, or chives and ultimately I went with chives because they have a more pronounced onion-y flavor. We tested this pasta with green onions too and it tastes just as good but I love the way chives look because they look like baby green onions.

How to make sour cream and onion pasta

1. Cook your pasta. Cook your favorite pasta shape according to the package in boiling salted water.

2. Make a roux. While your pasta is cooking, make the sour cream and onion sauce by melting some butter in a pan. When the butter is melted, stir in some flour to create a roux (see tips below).

3. Add milk. When the roux is cooked, stir in the milk and let the sauce thicken.

4. Add the sour cream. Take the sauce off the heat and stir in the sour cream.

5. Add the onions. By now your pasta should be done, so drain it and add it to the sauce. Stir in the chives, salt, and pepper, and enjoy!

How to Make a Roux

The key to a really smooth creamy white sauce (béchamel) is making sure that the roux is well mixed and cooked. When you are adding the flour to the just melted butter, sprinkle it on evenly, instead of just dumping it in a clump in the middle of the pan. Sprinkling the flour ensures that all of the flour kernels are coated with butter which helps them emulsify into the sauce smoothly. When the roux is cooked – it will turn a very slight creamy color, be texture of white sand, and smell a little nutty – it will take about 2 minutes. Using a whisk, it really helps move everything around. A well cooked roux will turn into a beautiful creamy white sauce perfect for pairing with pasta.

    Haven’t tried yet but thinking about it.
    I wonder, though, what your thoughts are on making a roux or any milk-based sauce with Lactaid or another lactose-free milk. I tend to find they never quite thicken up – and some recipes don’t work at all with them. Any tips or tricks?
    It’s hard to justify buying “normal” milk for one or two recipes when both of us in the house can’t drink it.

    1. Stephanie says:

      hi cody,
      i did a quick google and it looks like people successfully use milk based sauces with lactose-free milk – i haven’t experimented much with lactaid but i suspect that if you up the ratio of the flour to butter it might help thicken it up. what did the other sauces that didn’t thicken up look like? did they thicken at all or did the milk not whisk in?

      1. Cody says:

        It tends to stay thin. It makes me think about dough with/without gluten and how temperamental it can be if you overwork or underwork or don’t have the right amounts of gluten/yeast/etc.

        I may try again, but play with the ratio like you suggested as well as the heat.

        1. Anissa Alexander says:

          I have found that fairlife, another lactose free milk brand has worked better for me. I find that other lactaid tends to go sweet in my sauces but generally does thicken up. Fairlife doesn’t have this issue, which works when I am making something for family that can’t have lactose.

  3. Parth says:

    there wasn’t any addition of onion in the recipe part
    do we add sautéed onions?

    do we add sautéed onions?

    1. Stephanie says:

      hi parth,
      there are no sautéed onions in this recipe, but that sounds like a great addition. since it’s a take on sour cream and onion chips, the “onions” are actually chives :)

    I made mine with garlic powder, onion powder, and red pepper flakes. I added chicken and broccoli in there as well as raw green onion. It was really good!

  6. J Cole says:

    Is this recipe suitable for freezing ?

    1. Stephanie says:

      unfortunately the sauce won’t hold well frozen!

    Delicious recipe! I used non dairy milk and non dairy sour cream and it came out great!

    1. John Eric Hess says:

      Thank you for this comment. I’m looking to make it for my vegan girlfriend and was wondering about how it’d come out.

    I loved this simple recipe. I made a few changes to ratios, and added some extra veg and chicken to make this a nice complete meal. We have kids with severe lactose intolerance so we are able to make a nice creamy pasta dish with lactose free products with this receipe! :) thanks!

    I just made this tonight. I don’t use or buy regular milk so I made it with oat milk and Greek yogurt. I added grilled chicken and sautéed onions. Served with grilled asparagus it was a great hot summer night meal.

  14. David Hudson says:

    What about adding parmesan before serving?

    1. Stephanie says:

      you definitely can add some into the sauce after it’s thickened!

    This is pretty good! For more protein, I fried chicken in cajun seasoning. Goes well with this sauce.

  16. James says:

    Gonna try this, it looks delicious and I also love sour cream and onion chips. Would ready made bechamel work? Or is it better to be made?

    1. Stephanie says:

      i haven’t tried with ready made béchamel, i would just make the recipe as is :)

    Love this! I made it for dinner a few nights ago and making it again this week! I used almond milk and green onions. I also added some garlic powder into it. We used pasta we had on hand which was spaghetti, will be using penne this week to see how it is. Spaghetti wasn’t a bad pasta to use. I used may be 3/4 cup of water as well but I used way more than 5oz of pasta, but it did not lose flavor or dim it down at all!
    This will become a staple, honestly tastes better leftover and reheated. I think the green onions really permeated the sauce the more it sat and soften up. A few days afterwards was the best! I always wonder what to do with barely used sour cream and it goes to waste half the time.
