There’s nothing quite like pulling a bubbling pasta bake out of the oven – the top golden and crispy while the inside is creamy, comforting, and packed full of flavour. This version is one of my favourite low nickel recipes, naturally gluten free and dairy free options that sneaks in extra vegetables by blending them into a smooth, golden sauce that coats every piece of pasta. It’s hearty enough to stand alone as a meat-free dinner, but you can also stir through your favourite protein—like tuna, chicken, or even tofu—to make it extra filling.
I’ll be honest – I’ve never been the biggest fan of pasta or spaghetti – mostly because they can feel so carb-heavy and often leave me feeling lethargic or cause my blood sugar to spike. But this hidden veggie pasta bake is not like that. The creamy, blended sauce adds so much bulk and fibre that it kept me full and satisfied for hours, even without adding extra protein. The flavours from the carrots, cauliflower, celery, and turmeric make it surprisingly rich and comforting, mimicking the look and taste of a golden cheesy sauce, while the crispy golden topping adds a textural contrast that makes each bite feel really indulgent.
Another thing I really love about this recipe is how versatile it is. You can keep it fully vegetarian or vegan, or add in your favourite protein to make it a more substantial meal, and it makes enough to feed a crowd. It’s also naturally gluten-free, dairy-free, and low FODMAP, and it even counts as a nickel free recipe making it really suitable for a variety of dietary needs.
Even picky eaters or those who usually avoid veggies will love this version – they are well hidden! It’s a great way to sneak in more vegetables without feeling like you’re eating a salad. The sauce is completely smooth, so kids or adults who usually shy away from cauliflower or celery will happily eat it. And while it’s nourishing, it still feels like a proper comfort food—warm, filling, and satisfying, with a top layer that comes out beautifully crispy every time.
This pasta bake is perfect for a cozy weeknight dinner, batch cooking for lunches throughout the week, or a great option for an allergy safe party food (just check for egg in the pasta as this is a common allergen). Leftovers reheat beautifully, and the crispy topping still retains a little crunch if you pop it in the oven again. For me, it strikes the perfect balance between nourishing and indulgent; comfort food that actually leaves you feeling good afterwards.
Low Nickel-Friendly Comfort Food for Those On the SNAS Diet
Finding meals that are both comforting and low nickel can feel tricky, but I created this pasta bake specifically so that it would hit the sweet spot for low nickel diets too. Instead of relying on high-nickel ingredients like legumes or nuts, the creamy sauce is packed with veggies that are gentle for those sensitive to nickel.
Even on a low-nickel diet, you don’t have to sacrifice flavour or texture. The sauce is smooth and rich, the pasta is tender, and the golden, crispy topping adds that indulgent comfort food element we all crave. It’s a simple, satisfying dinner that works for nickel-free diets, as well as being naturally gluten-free, dairy-free, and low FODMAP.

Ingredients
- 250g gluten-free penne pasta
- 3 carrots, peeled and roughly chopped
- ¼ head cauliflower, chopped
- 2 celery stalks, chopped
- 2 green onion tops (green part only, for low FODMAP)
- ½ cup water
- 3 tbsp Nuttelex (or other dairy-free spread)
- 3 tbsp cornstarch mixed with 2 tbsp water to create a slurry
- 1 tsp turmeric
- 1 tsp Massel chicken stock powder (or vegetable, for vegetarian option)
- Salt & pepper, to taste
Optional add-ins:
- 1–2 cans tuna
- Cooked minced meat or pork
- Shredded chicken
- 1–2 whisked eggs
For the topping:
- Gluten-free breadcrumbs or GF panko + drizzle of olive oil
- Or dairy-free cheese of your choice
Method
- Cook the pasta
Boil pasta in salted water until al dente according to package instructions. Drain and set aside. - Make the veggie sauce
In a medium pot, add carrots, cauliflower, celery, and green onion tops with ½ cup water. Cook until the vegetables are soft, about 10 – 15 minutes.
Turn off the heat, then add Nuttelex, cornstarch slurry, turmeric, stock powder, salt, and pepper. Use an immersion blender in the pot to create a smooth and creamy texture.
Important: Hot liquids can cause dangerous burns as they create pressure and can splatter when placed in a normal blender – which is why I recommend an immersion blender for this step instead. Alternatively, to avoid burns, let the vegetables cool fully before transferring to a normal blender. - Assemble the bake
Spread the cooked pasta in a baking dish. Pour the blended sauce over and stir well. Add any protein if using, then flatten the top with a spatula. - Top it off
Scatter over breadcrumbs or GF panko, drizzle with olive oil, or add dairy-free cheese. - Bake until crispy
Bake covered at 200°C for 20 minutes, then uncover and bake for another 15 minutes until the top is golden, crunchy, and irresistible.
Notes
- This bake is crispy on top, creamy underneath, and deeply comforting—perfect for cosy nights.
- Naturally gluten free, dairy free, low FODMAP (with green onion tops only), and low nickel friendly.
- Great meat-free, but also works beautifully with tuna, chicken, or minced pork stirred through.
- Leftovers reheat well, and the crispy top holds its crunch surprisingly well.
FAQs
Can I freeze this pasta bake?
No I would avoid freezing it as pasta can tend to lose it texture after freezing and reheating. In my experience it doesn’t last long enough anyway!
Can I make it ahead?
Absolutely. Assemble the pasta and sauce in the dish, cover and allow to cool to room temperature, then refrigerate for up to 24 hours before topping with fresh breadcrumbs and baking. Just add a few extra minutes in the oven.
What pasta works best?
Any sturdy gluten-free pasta that holds its shape when baked. Penne, spirals, or shells are my favourites but you could even try spaghetti or something if you’re feeling experimental!
How do I make it fully vegetarian or vegan?
This recipe is already completely vegan if you don’t add in the optional meat proteins. The “chicken stock” in the ingredients might look misleading, but I use Massel chicken-style stock powder, which is actually plant-based and vegan-friendly (one of my pantry staples!).
What makes this low FODMAP?
The sauce uses only the green tops of spring onions for flavour, no garlic or onion. Massel stock is also FODMAP friendly.
What makes this pasta bake low nickel?
Nickel is a naturally occurring metal that’s found in many plant-based foods, especially legumes (beans, lentils, soy), whole grains, nuts, seeds, chocolate, and some leafy greens. For people who are sensitive to nickel, avoiding those foods can help reduce symptoms.
This pasta bake is low nickel because the creamy sauce is made with low nickel vegetables like carrots, cauliflower, and celery, and the toppings and add-ins can easily be chosen to stay low nickel (e.g. tuna, chicken, or pork instead of legumes or soy proteins).
It’s a great option if you’re following a low nickel diet but still want a hearty, comforting pasta dish.
