Key Ingredients

The Pasta Base

• 16 oz elbow macaroni (uncooked)
• 4 cups unsweetened plant milk (I prefer oat milk for its creaminess)
• 2 cups vegetable broth

The Cheese Sauce

• 2 cups raw cashews, soaked
• 1 large yellow onion, diced
• 4 cloves garlic, minced
• 1 cup nutritional yeast
• 2 tablespoons white miso paste
• 1 tablespoon apple cider vinegar
• 1 teaspoon smoked paprika
• 1/2 teaspoon turmeric (for color)

Optional Toppings

• 1 cup panko breadcrumbs (gluten-free if needed)
• 2 tablespoons vegan butter, melted
• Fresh thyme leaves
• Cracked black pepper

Let’s talk about why each ingredient matters. The cashews create that luxurious, creamy base we’re after, while nutritional yeast brings that classic cheesy flavor. The miso paste? That’s our secret weapon for depth and umami. Trust me, once you try this combination, you’ll never look back.

Step-by-Step Instructions

Preparing the Cheese Sauce

1. Soak the cashews overnight, or for at least 4 hours. In a pinch, you can cover them with boiling water and soak for 1 hour.
2. Drain and rinse the cashews, then blend them with 2 cups of the oat milk until completely smooth. This might take 2-3 minutes depending on your blender.
3. Add the nutritional yeast, miso paste, apple cider vinegar, smoked paprika, and turmeric to the blender. Blend until combined.

Slow Cooker Assembly

1. Grease your slow cooker insert with a light coating of oil or vegan butter.
2. Add the diced onion and minced garlic to the bottom of the slow cooker.
3. Pour in the uncooked macaroni, followed by the remaining oat milk and vegetable broth.
4. Pour the cheese sauce mixture over everything. Stir gently to combine.

Cooking Process

1. Cover and cook on LOW for 2-3 hours, stirring once halfway through.
2. Check the pasta at the 2-hour mark. It should be al dente but not mushy.
3. Once the pasta is cooked, stir thoroughly to combine all ingredients. The sauce will thicken as it stands.

Optional Crispy Topping

1. Mix panko breadcrumbs with melted vegan butter.
2. Sprinkle over the mac and cheese during the last 30 minutes of cooking.
3. Leave the slow cooker uncovered for the final 30 minutes if you want a crispy top.

Pro Tips and Common Mistakes to Avoid

After making this recipe countless times (and learning from my fair share of mishaps), here are my top tips:

Do’s

• Stir halfway through cooking to prevent sticking
• Use a high-quality nutritional yeast for the best cheesy flavor
• Keep the lid closed as much as possible to maintain consistent heat
• Let it rest for 10 minutes after cooking to achieve the perfect consistency

Don’ts

• Don’t overcook! This is the number one mistake that leads to mushy pasta
• Avoid lifting the lid too often, as this releases essential heat and moisture
• Don’t skip soaking the cashews – this is crucial for smooth sauce
• Don’t use coconut milk as your plant milk base (unless you want coconut-flavored mac!)
