Ultimate Green Vegan Mac and Cheese: A Healthy, Naturally Colored Delight
While I don’t typically go all out for St. Patrick’s Day, it’s always a wonderful excuse to add some vibrant green to our plates. Perhaps as my son, Hugo, gets a bit older, the festivities will become a bigger deal, but for now, it’s the perfect opportunity to indulge in delicious, naturally green food. And what better way to do that than with this incredible Green Vegan Mac and Cheese?

When I say “naturally green,” I mean it. We’re talking about the rich, vibrant hues derived directly from nourishing vegetables and herbs, not a single drop of artificial food coloring. This spectacular green vegan mac and cheese gets its beautiful color and incredible flavor from fresh pesto, unique romanesco broccoli, and tender baby spinach. It’s a healthy, plant-based twist on a classic comfort food that’s perfect for anyone looking for a dairy-free and gluten-free option.
The Secret to a Creamy Green Sauce: Romanesco Broccoli
Many traditional vegan mac and cheese recipes rely on potatoes for that essential creamy texture. However, I found myself wanting a lighter, less starchy alternative to coat our delicious pasta. My inspiration struck from a fantastic cauliflower cream pasta recipe in the “Thug Kitchen” cookbook (seriously, check it out if you haven’t!). This led me to a brilliant idea: incorporating romanesco broccoli directly into the sauce!

If you haven’t tried romanesco before, don’t let its striking, almost alien-like appearance intimidate you. I promise, it only looks like something from outer space, but it’s genuinely delicious! Imagine a delightful cross between cauliflower and broccoli, with a slightly nutty and earthy flavor. It’s surprisingly versatile and has become one of Hugo’s favorite vegetables, making it an excellent addition to this kid-friendly mac and cheese. Beyond its unique taste and texture, romanesco broccoli is packed with essential nutrients like Vitamin C, Vitamin K, fiber, and carotenoids, adding an extra layer of health benefits to your meal.
Roasting for Depth of Flavor
To really bring out the best in the romanesco and to achieve a wonderfully creamy, rich sauce without being overly heavy, I roast it in the oven. Alongside the romanesco florets, I roast an entire head of garlic. Roasting transforms the garlic, making it sweet, mellow, and spreadable, a stark contrast to its raw pungent flavor. Once roasted, these ingredients are blended into the “cheese” sauce, contributing significantly to its luscious texture and depth of flavor, making this dairy-free mac and cheese truly exceptional.

The Quest for the Perfect Gluten-Free Pasta
Living in Japan, finding truly excellent gluten-free pasta can be a bit of a challenge. While we don’t have pasta as often as we used to, when we do, I want it to be perfect. My past experiences with local corn pasta and Costco’s kale pasta left a lot to be desired – both were disappointingly mealy and far from the ideal texture. However, my search for the holy grail of gluten-free pasta finally led me to a winner: the organic brown rice pasta from Jovial Foods. Seriously, it’s the bomb dot com (yes, people still say that, especially when something is this good!).
For classic mac and cheese, elbow pasta is usually the go-to shape because its curves perfectly capture the creamy sauce. Unfortunately, it was out of stock during my last shopping trip, so I opted for penne instead. And you know what? It was still absolutely delicious! The ridged surface of the penne holds onto the green vegan cheese sauce beautifully, ensuring every bite is packed with flavor. This goes to show that while traditional shapes have their charm, a high-quality gluten-free pasta paired with an amazing sauce will always deliver a satisfying meal.

Why This Green Vegan Mac and Cheese Is a Winner
I genuinely adore this green vegan mac and cheese recipe for so many reasons. First and foremost, it’s incredibly EASY to prepare! The rich, creamy sauce comes together effortlessly in a blender. Plus, for added convenience and a boost of fresh veggies, you can boil the snap peas (or any vegetable of your choice) right alongside the pasta during the last few minutes of cooking. This means fewer pots to wash and a quicker path to a satisfying meal.
Beyond its simplicity, one of the biggest benefits for me is how wonderful I feel after eating it. As a dairy-free and gluten-free dish, it avoids the sluggish, heavy feeling that can sometimes accompany traditional mac and cheese. Instead, I feel energized and nourished, knowing I’ve enjoyed a wholesome, vegetable-packed meal that still delivers on comfort and flavor. It’s the perfect balance of indulgence and health, making it an ideal weeknight dinner or a special treat.
A Non-Vegan’s Honest Take
Now, as someone who isn’t strictly vegan, I won’t pretend that this green vegan mac and cheese tastes exactly like its dairy-laden counterpart. It’s important to set realistic expectations. Instead, I prefer to think of all vegan mac and cheese variations as their own distinct and delicious dishes, separate from the original. They offer a unique culinary experience that stands on its own merits.
However, when it comes to homemade vegan mac and cheeses, I can confidently say that this particular recipe is pretty damn good! The combination of roasted romanesco and garlic, blended with cashews, nutritional yeast, and vibrant pesto, creates a sauce that is surprisingly cheesy, incredibly creamy, and bursting with fresh, earthy flavors. It’s a comforting, satisfying meal that truly hits the spot, whether you’re vegan, gluten-free, or simply looking for a healthier, flavorful alternative.

Kid-Approved: A St. Patrick’s Day Success!
So, what’s your take? Do you think your kids would be delighted (or perhaps even fooled!) into eating this vibrant green vegan mac and cheese this St. Patrick’s Day, or any day for that matter? My other son, Tristan, usually isn’t the biggest fan of romanesco, which is a bit of a “boohockey” (I’m trying out some mom-friendly curse words!) since I love adding it to various dishes. However, much to my surprise and delight, he absolutely loved this green vegan mac and cheese! He devoured his portion and has already started asking when we’ll be having it again. This is high praise from a discerning palate and a testament to how appealing and delicious this plant-based dish truly is.

Ingredients
- 1 head of garlic
- 1 cup romanesco broccoli florets
- drizzle of olive oil
- pinch of salt
- ½ cup (120ml) raw cashews, soaked in water overnight
- 2 handfuls baby spinach
- ¾ cup (180ml) unsweetened almond milk
- 3 tablespoons nutritional yeast
- 1 tablespoon Dijon mustard
- 2 teaspoons apple cider vinegar
- 3 tablespoons vegan pesto
- 12 oz (340g) gluten-free short cut pasta (such as penne or elbow)
- 2 cups (480ml) sugar snap peas (optional, for added freshness)
Instructions
-
Preheat your oven to 400°F (200°C).
-
Prepare the garlic and romanesco: Without peeling the garlic, slice the whole head of garlic in half horizontally. Drizzle a little olive oil over the exposed cut surfaces, then sprinkle with a pinch of salt. Reassemble the garlic head halves and wrap tightly in aluminum foil. Place the romanesco florets in a separate piece of aluminum foil and also wrap them securely. Place both foil packets on a baking sheet and bake in the preheated oven for 45 minutes, or until both are tender. Once baked, set them aside to cool slightly.
-
Cook the pasta: While the garlic and romanesco are cooling, bring a large pot of salted water to a rolling boil. Add your chosen gluten-free pasta and cook according to package instructions. For added vegetables, incorporate the sugar snap peas (or any other quick-cooking vegetable) during the last 3 minutes of the pasta’s cooking time.
-
Make the green cheese sauce: Once the roasted garlic is cool enough to handle, gently press on the bottom of each clove to easily push the softened garlic out of its skin. Transfer all the roasted garlic cloves, romanesco florets, and the rest of the sauce ingredients (soaked cashews, baby spinach, unsweetened almond milk, nutritional yeast, Dijon mustard, apple cider vinegar, and vegan pesto) into a high-speed blender. Purée until the sauce is completely smooth and creamy, with no visible lumps.
-
Combine and serve: Drain the cooked pasta and snap peas thoroughly. Return them to the pot (with the heat turned off). Pour the freshly blended green cheese sauce over the pasta and vegetables. Stir gently until everything is evenly coated. Serve immediately while hot and enjoy!

Serving Suggestions and Make-Ahead Tips
This Green Vegan Mac and Cheese is hearty enough to be a complete meal on its own, but it also pairs wonderfully with a crisp side salad or some extra steamed greens.

If you’re planning a St. Patrick’s Day feast, it would make a fantastic vibrant centerpiece alongside other green-themed dishes.
While best enjoyed fresh, leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm on the stovetop over low heat, adding a splash of almond milk or water to restore its creamy consistency. This dish also makes a great option for meal prepping, allowing you to enjoy healthy, flavorful vegan comfort food throughout your busy week.
