Why You'll Love This Recipe
About the Ingredients
1.5 lbs (680g) boneless, skinless chicken breasts, sliced thin
Slicing thin ensures quick, even cooking. Substitute with chicken thighs for more juiciness.
2 tbsp (30ml) olive oil, divided
Use extra-virgin olive oil for best flavor. Can substitute with avocado oil.
8 oz (225g) cremini mushrooms, sliced
Cremini have deeper flavor than white button. Swap with shiitake or baby bellas.
3 cloves garlic, minced
Fresh garlic is best. Pre-minced works in a pinch, but use less (1 tsp).
1 cup (240ml) heavy cream
For a lighter version, use half-and-half or evaporated milk, but sauce will be thinner.
1/2 cup (120ml) chicken broth
Low-sodium preferred to control salt. Vegetable broth works too.
1/2 cup (50g) grated Parmesan cheese
Freshly grated melts better. Pre-shredded may contain anti-caking agents.
5 oz (140g) fresh baby spinach
Baby spinach wilts quickly. Frozen spinach can be used, but thaw and squeeze dry.
1 tsp dried thyme
Dried thyme adds earthiness. Use 1 tbsp fresh if you have it.
Salt and black pepper, to taste
Season generously; the sauce needs it.
Tips & Tricks
- Don't overcrowd the pan when searing chicken—cook in batches so it browns, not steams.
- Slice chicken evenly to ensure uniform cooking; pound to even thickness if needed.
- For a thicker sauce, let it simmer a few extra minutes to reduce, or stir in a slurry of cornstarch and water.
Pro Tips
Step-by-Step Instructions
1. Season and Sear Chicken
Pat chicken dry and season with salt and pepper. Heat 1 tbsp olive oil in a large skillet over medium-high heat (375°F/190°C). Add chicken in a single layer and cook for 3-4 minutes per side until golden brown and cooked through (internal temp 165°F/74°C). Remove and set aside.
2. Sauté Mushrooms
In the same skillet, add remaining 1 tbsp oil. Add mushrooms and cook undisturbed for 3-4 minutes until browned, then stir and cook 2 more minutes. Season with a pinch of salt.
3. Add Garlic and Thyme
Stir in minced garlic and dried thyme. Cook for 30 seconds until fragrant, stirring constantly to prevent burning.
4. Make the Cream Sauce
Pour in chicken broth and scrape up any browned bits from the bottom. Bring to a simmer, then reduce heat to medium-low (300°F/150°C) and stir in heavy cream. Simmer gently for 2-3 minutes until slightly thickened.
5. Melt Parmesan
Whisk in Parmesan cheese until fully melted and sauce is smooth. Taste and adjust seasoning with salt and pepper.
6. Wilt Spinach
Add spinach in handfuls, stirring until wilted, about 1-2 minutes total. The spinach will shrink significantly.
7. Combine and Serve
Return chicken to the skillet, spooning sauce over it. Cook for 2-3 minutes until heated through. Serve immediately over pasta, rice, or with crusty bread.
Delicious Variations
Make it low-carb
Serve over cauliflower rice or zucchini noodles instead of pasta.
Add a kick
Stir in 1/2 tsp red pepper flakes or a splash of hot sauce with the garlic.
Swap the protein
Use shrimp or tofu instead of chicken—adjust cooking times accordingly.
How to Store Chicken Mushroom And Spinach Recipes
Refrigerator
Store in an airtight container for up to 3 days.
Freezer
Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge.
Reheating
Reheat gently on the stovetop over medium-low heat, adding a splash of broth or cream to restore sauce consistency.
Frequently Asked Questions
Q: Can I use frozen spinach instead of fresh?
Yes, you can use frozen spinach. Thaw it first and squeeze out excess moisture before adding it to the skillet. Reduce the amount to about 1/2 cup (thawed) since frozen spinach is more concentrated.
Q: What can I substitute for heavy cream?
You can use half-and-half or whole milk mixed with a little flour or cornstarch to thicken. For a dairy-free option, use full-fat coconut milk, but it will add a slight coconut flavor.
Q: How do I prevent the sauce from curdling?
To avoid curdling, keep the heat at medium-low when adding cream, and don't let it boil vigorously. Also, add the cream slowly while stirring constantly.
Q: Can I make this dairy-free?
Yes, use olive oil instead of butter (if any), a dairy-free cream alternative like coconut cream, and nutritional yeast or dairy-free Parmesan for the cheesy flavor.
Q: What goes well with this dish?
This dish pairs well with pasta, rice, mashed potatoes, or crusty bread. For a low-carb option, serve over cauliflower rice or a bed of extra greens.
