Mushroom Bolognese Recipe

This Mushroom Bolognese recipe brings together finely chopped mushrooms, aromatic vegetables, San Marzano tomatoes, white wine, milk, basil, rigatoni, and Parmesan for a hearty vegetarian pasta dish with deep comfort-food flavour. Featured on Bring on the Karbs, this recipe captures the nostalgic, carb-loving spirit of Erika and Josh Karbelnik with a rich sauce that feels classic, satisfying, and perfect for a cozy meal at home.

The Inspiration

Bolognese is one of the most beloved comfort sauces in Italian-inspired cooking, traditionally built with a slow-cooked base of meat, aromatics, wine, tomato, and dairy. This Mushroom Bolognese takes that familiar structure and gives it a deeply savoury vegetarian twist by using finely pulsed button mushrooms in place of ground meat. The result is a sauce that feels hearty and substantial while still letting the earthy flavour of mushrooms shine. It is comforting, nostalgic, and exactly the kind of carb-forward dish that fits beautifully into Bring on the Karbs.

As with all recipes featured in this episode of Bring on the Karbs, this Mushroom Bolognese was improvised by Erika and Josh Karbelnik, and the recipe below is an approximation of what unfolded during the episode. That improvisational quality is part of what makes the dish so appealing. It encourages home cooks to embrace the process of building flavour slowly, tasting along the way, and turning humble ingredients into something memorable.

Ingredients

4 lbs button mushrooms
2 carrots
4 celery stalks
2 Spanish onions
4 cloves garlic
1 cup white wine such as Chardonnay
1 (28 oz) can San Marzano tomatoes
1/2 cup whole milk
1 bunch fresh basil
4 cups (1/2 L) dried rigatoni
6 oz Parmesan cheese
4 tbsp olive oil

Method

In a food processor add mushrooms and garlic. Pulse until ground beef consistency and remove from the food processor.
Pulse carrots and celery in the food processor. Small dice onion. Crush can tomatoes with hands.
Heat pan with olive oil over medium heat and add mushrooms, onions, carrots, and celery. Cook for 10 minutes, stirring occasionally.
Add white wine and reduce by half.
Add tomatoes and most of the basil. Cook on low for 1 hour, then add milk and cook for another hour.
Cook rigatoni in boiling salted water according to package instructions. Strain, plate, and top with sauce. Finish with parmesan and basil leaves and serve.

Serving Suggestions

Because the sauce is hearty and slow-simmered, it pairs beautifully with a crisp green salad dressed with lemon vinaigrette, roasted broccolini, garlic bread, focaccia, grilled vegetables, or a simple plate of marinated olives. For a fuller Italian-inspired meal, serve it alongside burrata, caprese salad, bruschetta, or roasted peppers.

If serving for guests, bring the sauce and pasta to the table separately and let everyone build their own bowl with plenty of Parmesan and fresh basil. The dish also works well family-style in a large serving bowl, topped with extra cheese and herbs for a generous, rustic presentation.

Its comforting texture and deep flavour make it satisfying enough to serve as the main event, especially when paired with bread for scooping up every last bit of sauce.

Final Thoughts

As featured on Bring on the Karbs, this dish reflects the playful and heartfelt cooking style of Erika and Josh Karbelnik. The episode “Childhood Memories” is an ideal setting for a recipe like this, because pasta has a way of connecting people to family tables, familiar flavours, and meals that feel generous and grounding. Even though this version is vegetarian, it still carries the emotional weight of a classic comfort dish. It is warm, filling, and made for sharing.
