This chicken, mushroom and tarragon pasta bake is my ultimate comfort food makeover. I discovered this lighter version of the classic when I was trying to create something creamy and satisfying without all the heavy cream. The combination of tender chicken, earthy mushrooms, and that subtle licorice hint from tarragon creates something that tastes totally indulgent but won't weigh you down.
Last month, I brought this to a potluck and three people asked for the recipe. Even my friend who 'doesn't do healthy food' went back for seconds!
Gather These Ingredients:
- Chicken breast: - get them fresh from the butcher if you can
- Baby bella mushrooms: - they have more flavor than white ones
- Fresh garlic and onion: - the base of all good things
- Fusilli pasta: - those spirals catch all the sauce perfectly
- Light cream cheese: - our secret weapon for creaminess
- Dijon mustard: for that subtle tang
- Dried tarragon: - don't skip this, it's the magic ingredient
- Real parmesan and cheddar: - worth spending a bit more on

Let's Create Magic:
- Prep Your Base:
- Start by getting your pasta water boiling and preheating your oven. I like to get all my ingredients lined up - it makes the whole process smoother.
- Build Your Flavors:
- Sauté those mushrooms until they're golden brown. This is where the magic starts - those caramelized edges add so much depth.
- Create Your Sauce:
- Here's where we get clever - using light cream cheese and stock to create a sauce that tastes rich but won't break the calorie bank. The Dijon mustard adds a subtle zip that makes everything pop.
- Bring It Together:
- Fold in that tarragon and watch how it transforms everything. When that aroma hits, your kitchen will smell like a French bistro.
- Add The Finishing Touch:
- Layer everything in your baking dish and top with both kinds of cheese. That golden, bubbly crust is what dreams are made of.
The first time I made this, my picky teen actually asked what that 'amazing smell' was. Now it's our Sunday night dinner tradition.
Perfect Pairings:
I love serving this with roasted green vegetables - the slight char complements the creamy pasta perfectly. A simple green salad with lemon dressing helps cut through the richness.
Make It Your Own:
Try adding spinach for extra nutrition, or swap in different mushroom varieties. Sometimes I'll add a pinch of red pepper flakes for heat, or stir in some sun-dried tomatoes for a flavor boost.
Keep It Fresh:
This actually gets better after a day in the fridge. Just add a splash of milk when reheating to bring back that creamy texture.

Kitchen Wisdom:
- Season each component as you go
- Don't overcook the pasta - it'll continue cooking in the oven
- Grate your own cheese for better melting
This recipe reminds me of the creamy pasta bakes my mom used to make, but with a grown-up twist. It's proof that comfort food can be both satisfying and sensible. Every time I make it, the house fills with those cozy aromas that just make everyone happy to be home for dinner.
