Step-by-Step Instructions

1. Caramelize the Onions:

Heat olive oil in a large pot or Dutch oven over medium-high heat. Add onions with ½ teaspoon salt and ½ teaspoon pepper. Reduce heat to medium and cook, stirring occasionally, for 25 to 35 minutes until golden brown and jammy. If onions stick, deglaze with a splash of water or broth.

2. Add Aromatics and Deglaze the Pot:

Stir in garlic and thyme. Cook for 1 to 2 minutes until fragrant.

3. Cook the Pasta:

Add broth, uncooked pasta, remaining salt, and pepper. Stir to combine. Bring to a boil, then reduce heat, cover, and simmer for 10 to 12 minutes, stirring occasionally, until pasta is tender.

4. Add the Cheese and Cream:

Remove lid. Stir in vegan mozzarella, heavy cream, and Dijon mustard. Mix until creamy and smooth. Taste and adjust seasoning.

5. Garnish and Enjoy!

Top with breadcrumbs, vegan parmesan and parsley. Serve hot and enjoy!

Tips and FAQs

• Caramelize patiently: The onions need time (25 to 35 minutes) to get deep golden and jammy. Don’t rush this step!
• Deglaze smartly: If onions stick, a splash of broth or water works wonders. White wine adds depth, but broth is a great substitute.
• Keep cheese creamy: Make sure vegan mozzarella and cream are at room temperature before adding so the sauce doesn’t seize up.
• Stir occasionally: Once pasta is simmering, stir now and then to prevent sticking.
• Make it extra indulgent: Top with vegan parmesan and parsley for restaurant-worthy presentation.

Can I use something other than vegan heavy cream?

You can use extra creamy plant-based milk, unsweetened cashew cream or full-fat coconut milk.

What can I sub the wine with?

You can replace it with extra broth for a non-alcoholic version.

What’s the best way to store leftovers?

Keep refrigerated in an airtight container for 3 to 4 days. Reheat gently on the stove or in the microwave, adding a splash of broth if needed.
