Why this recipe works
Mushrooms are often underrated, yet they make an excellent, flavourful base for vegetarian and vegan dishes. Their meaty texture and deep umami notes make them a natural choice when creating a gluten-free, dairy-free, meat-free stroganoff.
This recipe grew from a popular one-pot mushroom stroganoff and adds pasta for a hearty bake that still feels light and wholesome. The sauce, built from coconut milk, Dijon mustard and paprika, becomes creamy and well-seasoned while lemon and parsley add brightness to balance the richness.
It’s a simple, one-skillet-to-oven dish that’s great for meal prep or a quick weeknight dinner. Use a large oven-safe skillet if you want to make it entirely in one pan before finishing in the oven.
Ingredients to make Mushroom stroganoff pasta bake
- Mushrooms: Chestnut mushrooms are used here for flavour and colour, but baby bellas, portobellos or button mushrooms work too.
- Red onion: Adds a pleasant bite that complements the mushrooms and sauce.
- Garlic: Two cloves give a balanced garlic flavour; increase to taste if you prefer more.
- Olive oil: A light oil for sautéing the vegetables; avocado oil is an alternative.
- Dijon mustard: Provides tang and depth to the sauce; yellow mustard can be substituted in a pinch.
- Paprika: Adds colour and a gentle smokiness that pairs well with the mushrooms.
- Coconut milk: Full-fat coconut milk makes the sauce creamy and dairy-free; avoid low-fat versions for best texture.
- Fresh lemon juice: A splash of lemon brightens and balances the rich sauce.
- Fresh parsley: Chopped parsley adds freshness and colour.
- Pasta: Use gluten-free brown rice or chickpea pasta to keep the dish gluten-free; rotini or fusilli are ideal so the sauce clings to the spirals.
See the recipe card below for exact quantities.
Substitutions
- Milk alternative: If you prefer not to use coconut milk, substitute creamy cashew or oat milk for a similar texture.
- Alliums: If you don’t have red onion or garlic, minced shallots make a good replacement.
Variations
- Spicy: Add minced jalapeño, red pepper flakes or a pinch of cayenne for heat.
- Pasta shapes: Any short gluten-free pasta works — macaroni or shells are good alternatives to rotini.
Instructions to make Mushroom stroganoff pasta bake
Step 1: Slice the mushrooms, dice the red onion and mince the garlic.
Step 2: Heat olive oil in a skillet over medium heat. Add the mushrooms, onion and garlic, and cook until softened and browned, about 5 minutes.
Step 3: Add Dijon mustard, paprika, coconut milk, lemon juice, chopped parsley and the dry pasta. Stir to combine and simmer for 5 minutes to let the pasta start to absorb the sauce.
Step 4: Transfer the mixture to an ovenproof baking dish and bake at 200°C (fan) / 390°F for 15 minutes. Remove from the oven and serve warm with extra chopped parsley and a lemon wedge.
Hint: For a true one-pot meal, cook everything in a large oven-safe skillet (cast iron works well) and finish it in the oven.
Leftovers
Cool leftovers and store in an airtight container in the fridge for up to 3 days. Portion into individual containers for meal prep. This bake also freezes well—use an oven-safe or foil dish so reheating is simple. Thaw before reheating and bake until piping hot.
Recipe FAQs
Yes. Cooking the pasta beforehand means you can skip the baking step, but simmer the combined ingredients briefly so the pasta soaks up the sauce and mushrooms. Stir occasionally to coat evenly.
Yes — it would become a rich, creamy mushroom side rather than a main course. You can also serve the stroganoff sauce over rice or mashed potatoes for a different meal option.

Instructions
-

-
Heat a non-stick pan with olive oil, add the mushrooms, onion and garlic, and fry until the mushrooms soften, about 5 minutes.
-
Stir in the mustard, paprika, coconut milk, lemon juice, parsley and raw pasta. Simmer for 5 minutes so the pasta begins to absorb the sauce.

Notes
Substitutions & Variations: See the list above for easy swaps and ways to change the flavour.
Storage: Keep in the fridge for up to 3 days. Freeze in suitable containers for up to 4 months; defrost and reheat until piping hot.
Tips: Rotini or fusilli work best to capture the sauce. Slice mushrooms evenly so they cook uniformly. Cover with foil if you prefer a less crispy top when baking.
