Asparagus Mushroom Pasta

This vegan Asparagus Mushroom Pasta is an easy and delicious gluten-free pasta dish. This one-pot dish with a light sauce takes less than thirty minutes to make, so you can enjoy it any day of the week!

What inspired me to make this dish was seeing all the beautiful and fresh spring produce available. The tender and thin stalks of young asparagus are among my favorite spring veggies. The slimmer asparagus taste the best to me, as they are so green, grassy, and fresh.

How to select asparagus

Although I prefer the thinner stalks of asparagus, the thicker ones will work fine in this recipe. Thickness is not an indicator of freshness but maturity. Avoid asparagus with woody stems, since they lack flavor and freshness.

You can use the thicker asparagus. Be sure to snap the ends off first. For the photo above I trimmed the asparagus evenly, but this is a step I usually skip.

Look for purplish tips and bright green color when you are shopping for asparagus. You can see a faint violet tinge in the tips of the asparagus above. Avoid the stalks with limp stems, since they should be firm.

Another indicator of freshness is closely tipped asparagus. Have you ever heard asparagus squeak when you grab a fresh bunch? That is how they should sound.

How to keep asparagus fresh

When you bring the asparagus home from the grocery store or the market, snap off the tough ends, as mentioned above. Fill a mason jar with water and place the asparagus in the jar upright so it can absorb the water through the snapped ends. I tried this recently and the asparagus was much fresher than it otherwise would have been. I'm going to do this from now on!

Which mushrooms do I use?

I came across these organic Japanese mushrooms which I ended up using in the pasta recipe. The white beech mushrooms pictured above, also known as bunapi mushrooms, are clean tasting and delicate. They are less earthy tasting than cremini or baby Portobello mushrooms.

The white beech mushrooms pair quite well with the grassy taste of the asparagus and the flavor of the fresh thyme. Pictured below are brown beech mushrooms, also known as bunashimeji, which are delicious in this recipe as well.

How do I select mushrooms?

Look for fresh mushrooms that are smooth, plump and firm. Avoid those that look dried out or damp. Many of the cremini and portobello mushrooms I see have exposed gills. Exposed gills means that they have a richer flavor than those with covered gills. Those with covered gills have a lighter and more delicate flavor. Keep this in mind if you choose these mushrooms.

You can use whichever variety of mushrooms is available. My favorite mushrooms are the white beech or brown beech mushrooms. I find that the cremini mushrooms overpower the asparagus with their earthiness and the flavor of the thyme is not as pronounced. However, feel free to try whichever mushrooms suit your taste!

🍽 Equipment

Here's what you will need to make this dish:

• medium saucepan with high sides
• wooden spoon
• cutting board
• chef's knife
• colander
• Microplane grater if using store-bought vegan Parmesan

🥘 Ingredients

To make this pasta, you will need:

• penne pasta - I chose brown rice gluten-free penne pasta
• asparagus
• garlic
• mushrooms - I chose white and brown beech mushrooms
• sea salt - I like to use Himalayan sea salt or Celtic sea salt
• extra-virgin olive oil
• fresh thyme - tips on how to destem fresh thyme are below
• vegan butter, or more extra-virgin olive oil
• vegan Parmesan (optional)
• a couple of tablespoons of water, vegetable stock, or white wine to deglaze the pan if needed

How do I destem fresh thyme?

Rinse the fresh thyme with stems in cold water and dry gently with a soft towel. Hold the top of the stem with your left hand and pull the leaves off in a downward motion with your right thumb and index finger. This will take the leaves off easily.

Crush the thyme leaves gently before adding them to the pasta to release the flavor.

If your thyme is fresh, the stems will be soft and they are edible. However, if your thyme is on the dry side, you can hydrate it by soaking it in cool water for about 10 minutes or so. If your thyme stems are woody, those are inedible.

🔪Instructions

• In a medium saucepan, boil water on medium heat. In the meantime, wash the asparagus, snap off the ends, chop the mushrooms and garlic, and measure the other ingredients so that they're ready to go when you start cooking.
• When water is boiling, add salt, then add the pasta and stir right away so the pasta doesn't stick to the saucepan. Cook the pasta up to 2 minutes before the recommended cook time period for the pasta. Stir occasionally.
• Two minutes before the pasta is done, add the asparagus to the pasta and water, and cook for 2 to 4 more minutes. Stir occasionally, until the asparagus turns bright green and the pasta water starts gently boiling again. 
• Drain the asparagus and pasta in a colander, and set aside, reserving about a half cup of water. Do not rinse the pasta.
• Place the empty saucepan back on medium heat. Add olive oil and when the oil starts to shimmer, add the garlic and stir continuously for 30 seconds. Do not let the garlic turn brown or it will taste bitter. If it starts turning golden, add the mushrooms and stir immediately.
• After adding mushrooms, stir, and add sea salt, vegan butter, and thyme. Sauté for a few minutes, stirring frequently on low-medium to medium heat. If you are seeing browned bits on the bottom of the saucepan, you can deglaze with a couple of tablespoons of the reserved pasta liquid. Or if you are enjoying white wine with your meal, try deglazing with wine instead.
• Stir in the pasta with asparagus that you set aside earlier. Add a couple of pinches of salt to taste. Keep stirring gently until everything is heated through.
• Serve immediately. Add freshly ground black pepper and grated vegan Parmesan if you wish. Garnish with sprigs of fresh thyme.

💭 Top tips

• Use the freshest vegetables you can find!
• Crush the thyme leaves gently before adding them to the pasta to release the flavor.
• Do not rinse the pasta once it is cooked.
• Be sure not to overcook the pasta.

♻️ Variations

Although I used gluten-free penne pasta, you may use whichever pasta you prefer. I like to experiment with different varieties of pasta. Our household is not gluten-free.

I love the 100% organic brown rice penne I used to make this asparagus and mushroom pasta.

Deglaze with white wine instead of water if you are enjoying wine with your meal, or use vegetable stock.

Storage

Refrigerate pasta within two hours of cooking in shallow airtight containers (I prefer glass) or resealable plastic bags. It will last for three to five days in the refrigerator.

Usually, you can freeze leftover pasta in covered airtight containers or heavy-duty freezer bags for one to two months. Since this pasta is very light on the sauce, I don't recommend freezing it since it may become mushy when thawed.
