Ingredients

Scale

Pasta

8 ounces spaghetti, cooked al dente

Proteins

4 ounces smoked turkey bacon, chopped
6 ounces cooked smoked turkey slices, chopped

Vegetables and Aromatics

1 cup mushrooms, sliced
1 medium onion, finely chopped
2 cloves garlic, minced

Sauce

2 cups plant-based milk
1 cup plant-based cheese, shredded or cubed
2 tablespoons vegetarian Worcestershire sauce (natural)
1 tablespoon apple cider vinegar (natural)
1 teaspoon natural gelling agent

Other

2 tablespoons olive oil
Salt, to taste
Black pepper, to taste

Instructions

Prepare and Cook the Pasta: Bring a large pot of salted water to a boil and cook the spaghetti until just al dente. Drain and toss with a little olive oil to prevent sticking while you prepare the sauce.
Sauté Aromatics and Mushrooms: In a large skillet, heat olive oil over medium heat. Add finely chopped onion and minced garlic, cooking until soft and fragrant. Stir in sliced mushrooms and cook until they release their juices and soften nicely.
Cook Smoked Turkey Bacon and Smoked Turkey: Add chopped smoked turkey bacon to the skillet, frying until crispy but tender. Then stir in chopped smoked turkey slices to warm through and merge the flavors.
Make the Creamy Sauce: In a separate saucepan, whisk together plant-based milk, plant-based cheese, vegetarian Worcestershire sauce (natural), apple cider vinegar (natural), and natural gelling agent over low heat until smooth and thickened. Season with salt and pepper.
Combine and Transfer to Baking Dish: Toss the cooked spaghetti, sautéed mixture, and creamy sauce gently together. Pour everything into a greased casserole dish and smooth the top evenly.
Bake and Serve: Bake the casserole in a preheated oven at 350°F (175°C) for about 25 to 30 minutes until bubbly and golden on top. Let it rest for a few minutes before serving to allow flavors to meld perfectly.

Notes

Cook spaghetti just until al dente to avoid mushy texture after baking.
Use fresh mushrooms for better flavor and moisture.
Prep ingredients ahead to make assembly quick and stress-free.
Adjust plant-based milk and natural gelling agent to control sauce thickness and creaminess.
Let the casserole rest briefly after baking so it sets and cools slightly for optimal serving temperature.
