Rain was tapping against my kitchen window last Tuesday when I realized I hadnt been to the grocery store in days. The fridge held exactly what I needed though chicken breasts, a carton of mushrooms going soft, and half a box of spaghettini. Sometimes the best meals happen when you stop overthinking and just start cooking. This dish came together in that lovely, unexpected way that feels like stumbling onto a secret you want to keep forever.

My sister called me halfway through making this, catching me mid stir at the stove. She could hear the sizzling and asked what smelled so good. When I described it, she said, "That sounds like the kind of dinner you eat standing up because you cant wait." Shes right. This is the kind of food that pulls people into the kitchen, asking, "Is it ready yet?" with genuine excitement.

Ingredients

  • Whole wheat spaghettini: The nutty flavor adds depth that regular pasta misses and it holds up beautifully when tossed with the sauce
  • Chicken breasts: Pounding them to even thickness is the trick I learned from my grandmother ensures every bite stays juicy
  • Cremini mushrooms: These little brown mushrooms have more flavor than white ones and develop this gorgeous golden color as they sauté
  • Low-fat milk: Creates a creamy base without the heaviness of cream, letting the other ingredients shine through
  • Fresh thyme: Something about thyme and mushrooms is just right, like they were always meant to be together
  • Dijon mustard: Dont skip this small addition it adds a subtle depth that makes people ask, "Whats your secret?"

Get your pasta water going first:
Drop that spaghettini into boiling salted water and cook it until its got a little bite left to it, then scoop out half a cup of the starchy water before draining.
Season and cook the chicken:
Pound those breasts until theyre an even thickness, season them generously, and sear them in hot olive oil until theyre golden and cooked through.
Build the flavor foundation:
In the same skillet, let the mushrooms and onions get soft and golden, then add the garlic and thyme until the kitchen smells incredible.
Create the creamy sauce base:
Sprinkle flour over the vegetables, stir it around for a minute, then whisk in the broth and milk until everything bubbles and thickens slightly.
Finish with finesse:
Stir in the Parmesan and mustard, season it perfectly, then toss everything together with the pasta and sliced chicken.

Last weekend, I made this for friends who swear they dont like cream sauces. They went back for seconds and asked for the recipe before leaving the table. Thats the thing about this dish it converts people without them realizing whats happening. The mushrooms do something magical that makes you forget youre eating something "lighter."

The Secret to Golden Mushrooms

After years of making mushrooms that looked more gray than appetizing, I finally stopped crowding the pan. Give them room and patience, let them sit undisturbed between stirs, and they develop this gorgeous brown color and nutty flavor that transforms the whole dish.

Sauce Timing Matters

I used to rush the sauce stage, whisking frantically and wondering why it tasted like flour. Now I let the flour cook with the vegetables for a full minute before adding liquid. That simple step removes any raw flour taste and gives the sauce a subtle nutty foundation.

Make It Your Own

This recipe welcomes substitutions like an old friend welcomes you home. Sometimes I add white beans for extra protein, other times a handful of arugula for peppery freshness. The sauce is forgiving and the technique stays the same.

  • A splash of white wine in the sauce adds brightness that cuts through the creaminess
  • Leftovers reheat beautifully with just a splash of milk to loosen the sauce
  • Fresh parsley is worth the extra chop it adds color and a fresh finish

Recipe FAQs

Can I make this ahead of time?

The sauce can be prepared up to 2 days in advance and stored in an airtight container. Reheat gently on the stovetop over medium heat, adding a splash of broth or milk if needed. Cook the pasta fresh just before serving to maintain its texture.

What type of mushrooms work best?

Cremini and white mushrooms are ideal for their mild, earthy flavor that complements the cream sauce. Baby bellas or shiitake mushrooms also work wonderfully for a richer, deeper taste. Avoid delicate varieties like oyster mushrooms, which can become too soft.

How can I make this sauce creamier?

Substitute half of the low-fat milk with half-and-half or heavy cream for a richer, more indulgent sauce. Alternatively, add a few tablespoons of cream cheese whisked into the warm sauce for extra smoothness and flavor.

Is this suitable for a gluten-free diet?

Yes! Use gluten-free spaghettini and gluten-free all-purpose flour in place of regular flour. Always verify that your chicken broth is gluten-free, as some brands contain hidden gluten. The rest of the ingredients are naturally gluten-free.

What pasta alternatives can I use?

Fettuccine, tagliatelle, or pappardelle pair beautifully with this creamy sauce. For a lower-carb option, try zucchini noodles or shirataki noodles, which won't hold the sauce the same way but still create a delicious lighter dish.

Can I add vegetables to this dish?

Absolutely! Spinach, peas, sun-dried tomatoes, or roasted bell peppers complement this sauce perfectly. Add tender vegetables like spinach in the final minute of cooking, or include heartier vegetables like broccoli or carrots during the sauté stage with the mushrooms.

02 Extra grated Parmesan cheese (optional)

Step-by-Step Directions

Step 01

Cook pasta: Bring a large pot of salted water to a boil. Cook spaghettini according to package directions until al dente. Reserve 1/2 cup pasta water, then drain and set aside.

Step 02

Prepare chicken: While pasta cooks, pound chicken breasts to even thickness. Season both sides with salt and pepper.

Step 03

Sear chicken: Heat olive oil in a large nonstick skillet over medium-high heat. Add chicken and cook 5 to 6 minutes per side until golden and cooked through. Remove to a plate, cover loosely, and let rest.

Step 04

Sauté vegetables: In the same skillet, reduce heat to medium. Add mushrooms and onion; sauté 4 to 5 minutes until softened and golden. Add garlic and thyme, cook 1 minute.

Step 05

Create roux: Sprinkle flour over vegetables and stir well. Cook 1 minute.

Step 06

Build sauce: Gradually whisk in chicken broth followed by milk, stirring to avoid lumps. Bring to gentle simmer and cook 2 to 3 minutes until slightly thickened.

Step 07

Finish sauce: Add Parmesan cheese and Dijon mustard; stir until smooth. Season with salt and pepper. Add spinach if using and stir until wilted.

Step 08

Combine components: Slice chicken into strips. Add cooked spaghettini and chicken to the sauce; toss gently to coat. Add reserved pasta water if needed for desired consistency.
