Ingredients Needed

This mushroom and spinach pasta recipe keeps things simple but bold. Here’s what you’ll need to whip up a batch:

• Pasta: 12 oz (340g) spaghetti, linguine, or bucatini (regular or black pasta for Halloween flair)
• Mushrooms: 10 oz (280g) cremini or button mushrooms, cleaned and sliced (portobello or shiitake work well too)
• Spinach: 5 oz (140g) fresh baby spinach, washed and roughly chopped
• Garlic: 3 cloves, minced (for that savory punch)
• Shallot: 1 small, finely diced (adds sweetness and depth)
• Olive Oil: 2 tbsp (30ml) extra virgin olive oil (use a good-quality brand for best flavor)
• Butter: 2 tbsp (28g), unsalted (adds richness)
• Vegetable Broth: 1/2 cup (120ml) (or chicken broth for non-vegetarian option)
• Heavy Cream: 1/3 cup (80ml) (for a creamy sauce—swap with coconut cream for dairy-free)
• Grated Parmesan Cheese: 1/2 cup (50g) (plus more for serving)
• Salt & Pepper: To taste (freshly cracked pepper is a must)
• Red Pepper Flakes: 1/4 tsp (optional—for a little heat)
• Lemon Zest: 1/2 tsp (adds brightness and balances richness)
• Fresh Parsley: 2 tbsp, chopped (for garnish and a pop of color)

Ingredient Notes: I love using cremini mushrooms for their earthy flavor, but feel free to mix in portobello or shiitake if you’re feeling fancy. Baby spinach wilts quickly and stays tender—if you only have regular spinach, just chop it finely. For the pasta, black spaghetti (squid ink) is a fun choice for Halloween, but any long noodle works great. If you need gluten-free, swap in your favorite alternative pasta. For a vegan version, use coconut cream and skip the Parmesan (nutritional yeast works well as a substitute).

Honestly, I’ve made this recipe with all sorts of tweaks—sometimes adding a handful of frozen peas or swapping shallots for sweet onions. The flavors are pretty forgiving. Just don’t skip the garlic—it really pulls everything together!

Equipment Needed

Here’s what you’ll need to make mushroom and spinach pasta:

• Large Pot: For boiling pasta. (Any sturdy pot will do!)
• Large Skillet or Sauté Pan: For cooking mushrooms, spinach, and sauce. Nonstick works well; cast iron adds extra browning.
• Colander: To drain pasta. Mesh strainers work too.
• Chef’s Knife & Cutting Board: For prepping mushrooms, spinach, and aromatics. A sharp knife makes quick work of it.
• Wooden Spoon or Spatula: To stir everything together.
• Microplane or Grater: For Parmesan and lemon zest.
• Measuring Cups & Spoons: For sauce ingredients.

Don’t worry if you don’t have a fancy skillet—just use your biggest, heaviest pan. I’ve made this with both nonstick and stainless steel, and both work well. If you’re low on budget, thrift stores are goldmines for sturdy pots and pans. And hey, if your colander has seen better days (like mine), a clean kitchen towel over a mesh strainer does the trick in a pinch. Just make sure all your tools are dry before you start—wet equipment makes things steam instead of sauté!

Preparation Method

1. Boil the Pasta:
   
   Bring a large pot of salted water to a rolling boil. Add 12 oz (340g) of pasta and cook according to package directions until al dente (usually 8-10 minutes). Reserve 1/2 cup (120ml) of pasta water before draining. Set pasta aside.
2. Sauté Mushrooms & Aromatics:
   
   While the pasta cooks, heat 2 tbsp (30ml) olive oil and 2 tbsp (28g) unsalted butter in a large skillet over medium-high heat. Add the diced shallot and sauté for about 2 minutes until softened. Toss in the minced garlic and cook for another 30 seconds, just until fragrant (don’t let it burn!).
3. Cook the Mushrooms:
   
   Add 10 oz (280g) sliced mushrooms to the skillet. Spread them out and let them cook undisturbed for 3 minutes (they’ll start to brown). Stir and continue cooking for another 3-4 minutes until mushrooms are golden and any liquid has evaporated. If the pan gets dry, add a splash of broth.
4. Wilt the Spinach:
   
   Add 5 oz (140g) chopped spinach to the skillet. Toss until just wilted (about 1-2 minutes). It should stay bright green—don’t overcook.
5. Make the Sauce:
   
   Pour in 1/2 cup (120ml) vegetable broth and 1/3 cup (80ml) heavy cream. Stir well, scraping up any browned bits from the bottom. Simmer for 2-3 minutes until slightly thickened. Add 1/2 cup (50g) grated Parmesan, salt, pepper, red pepper flakes, and lemon zest. Stir until the cheese melts and the sauce is creamy.
6. Add Pasta & Finish:
   
   Add the cooked pasta to the skillet. Toss everything together, adding reserved pasta water a little at a time until the sauce coats the noodles perfectly. Taste and adjust seasoning if needed.
7. Serve:
   
   Transfer to a serving bowl. Garnish with chopped parsley and extra Parmesan. Serve hot!

Preparation Notes: If the sauce seems thin, let it simmer a minute longer. If it’s too thick, add a splash more pasta water. The mushrooms should be deeply browned for maximum flavor—don’t rush this part! If you notice the spinach getting soggy, remove the skillet from heat as soon as it wilts. For extra Halloween flair, toss cooked pasta with a drop or two of black food coloring before adding the sauce (I’ve done this for parties, and it’s a huge hit!).

Cooking Tips & Techniques

Here are a few hard-won tips for mushroom and spinach pasta that I’ve learned the long way:

• Brown, Don’t Boil: Mushrooms release lots of water. Spread them out and let them brown—don’t just stir constantly or you’ll get soggy mushrooms.
• Layer the Flavors: Sautéing shallots first sweetens the base, and adding garlic just before mushrooms keeps the flavor punchy.
• Don’t Overcook Spinach: Spinach wilts in seconds. I once let it go too long and ended up with mushy greens—watch carefully!
• Reserve Pasta Water: This starchy liquid is your secret weapon for a silky sauce. Add slowly until the pasta is glossy and well-coated.
• Troubleshooting Cream Sauce: If the sauce splits or looks curdled, add more cream and whisk vigorously. Parmesan should be added off-heat for best melting.
• Timing is Everything: Start the sauce right as the pasta finishes boiling so nothing sits too long. Multitasking saves time and keeps things hot.

I’ve burned the garlic more times than I’d like to admit—so keep a close eye! And if the mushrooms look sad and pale, turn up the heat. Cooking everything in stages brings out the best flavors. For consistency? Always taste before serving. The salt level can change depending on your cheese and broth. Last tip: keep extra herbs handy for a fresh finish—parsley and chives work wonders!

Variations & Adaptations

Mushroom and spinach pasta is super flexible. Here are a few ways to switch it up for different tastes or dietary needs:

• Gluten-Free: Use your favorite gluten-free pasta. I like brown rice spaghetti—it holds up well and isn’t mushy.
• Vegan: Swap heavy cream for coconut cream or unsweetened oat milk. Use nutritional yeast instead of Parmesan for cheesy flavor.
• Protein Boost: Add cooked chickpeas or white beans for extra protein. Grilled chicken strips work well for non-vegetarians.
• Seasonal Flavor: Toss in roasted butternut squash or sweet potato cubes for a fall twist.
• Spicy Kick: Double the red pepper flakes, or add a splash of hot sauce in the sauce.
• Allergen Substitutions: For nut allergies, skip any nut-based Parmesan alternatives. Dairy-free cheese can be swapped in for lactose intolerance.

My personal favorite? Adding a handful of sun-dried tomatoes and some chopped walnuts. It gives a tangy, crunchy punch that’s perfect for autumn. If you’re making this for a crowd, offer a few toppings on the side—everyone loves to customize their own bowl!

Serving & Storage Suggestions

Serve mushroom and spinach pasta piping hot, straight from the skillet. For Halloween, I love piling it into a wide bowl and topping it with extra parsley and “spooky” black olives on the side. It pairs well with garlic bread or a simple mixed green salad. For drinks, a crisp white wine or sparkling water with a splash of lemon works wonders.

If you’re prepping ahead, store leftovers in an airtight container in the fridge for up to 3 days. The flavors actually deepen overnight, making it even tastier the next day! Reheat gently in a skillet over low heat, adding a splash of broth or water to loosen the sauce. You can freeze the sauce (without pasta) for up to a month—just thaw, reheat, and toss with fresh noodles.

One note: spinach can get a little watery after storing, so drain any excess liquid before reheating. This pasta is great for meal prep—just portion into containers and you’ve got lunch sorted for the week!

Yes, you can! Just thaw and squeeze out as much water as possible before adding it to the pan. The texture will be a bit softer, but the flavor’s still great.
