A Creamy, Comforting Pasta Sauce Packed with Hidden Vegetables
This is a bit of a sneaky one.
I wanted a creamy, comforting pasta dish, but I also wanted to pack some extra vegetables into dinner. So instead of leaving the vegetables chunky and obvious, I finely diced them, cooked them down into a creamy sauce and then blended the whole thing until completely smooth.
The result? A rich, creamy pasta sauce where you wouldn’t necessarily know there were loads of vegetables hiding inside.
I used filled tortellini this time, but you can use absolutely any pasta you like. Spaghetti, penne, fusilli or tagliatelle would all work beautifully.
It’s a little more involved than some of my super-quick recipes, but it’s still straightforward and makes a really comforting homemade dinner.
Recipe Details
Prep Time: 10 minutes
Cook Time: 30 minutes
Total Time: Around 40 minutes
Serves: 2
Difficulty: Easy
Ingredients
- 1 small white onion, finely diced
- 1 stick celery, finely diced
- Small handful of cabbage, finely diced
- ½ courgette, finely diced
- 1 tbsp butter
- Salt, to taste
- White pepper, to taste
- Maggi Liquid Seasoning, to taste
- 1 tbsp plain flour
- Around 250ml milk
- Splash of single cream, optional
- Small knob of cheddar cheese, optional
- 200–250g pasta or filled tortellini
Method
1. Prepare the Vegetables
Finely dice the onion, celery, cabbage and courgette.
The smaller you chop them, the quicker they will cook and the easier they will be to blend into the sauce.
2. Cook the Vegetables
Melt the butter in a large frying pan over a medium-low heat.
Add the diced vegetables and cook slowly until everything has softened.
Season with salt, white pepper and Maggi Liquid Seasoning to taste.
Take your time here – you want the vegetables soft rather than browned.
3. Make the Roux
Once the vegetables are soft, sprinkle over the flour and stir everything together.
The flour should coat the vegetables and form a slightly sticky paste.
4. Add the Milk
Slowly add the milk a little at a time, stirring continuously.
Adding it gradually helps prevent lumps and allows the sauce to thicken nicely.
Continue stirring until you have a creamy sauce.
5. Make It Extra Creamy
This part is completely optional.
Add a splash of single cream and a small knob of cheddar cheese.
Stir until the cheese has melted and everything is combined.
If you want to keep things lighter, simply leave both out.
6. Hide the Vegetables!
This is the fun bit.
Using a hand blender, carefully blend the sauce until completely smooth.
Blend until there are no obvious pieces of vegetable left.
Give it a taste and adjust the seasoning with more salt, white pepper or Maggi Liquid Seasoning if needed.
7. Cook the Pasta
Cook your chosen pasta according to the packet instructions.
I used filled tortellini, but any pasta works with this sauce.
Once cooked, drain well.
8. Combine
Add the cooked pasta to the creamy hidden vegetable sauce and stir everything together until well coated.
Serve immediately while hot.
Millie’s Notes
Use whatever vegetables you have. My combination was onion, celery, cabbage and courgette, but this is a great recipe for using up vegetables in the fridge.
Finely dice everything. This makes the vegetables easier to cook and helps create a completely smooth sauce once blended.
The cream and cheese are optional. The milk and vegetable sauce already create a creamy base, so you can leave them out if you want a lighter version.
Don’t rush the roux. Add the milk gradually while stirring to create a smooth, creamy sauce without lumps.
Use any pasta you like. I used filled tortellini, but spaghetti, penne, fusilli or tagliatelle would all work.
Why I Love This Recipe
It’s creamy, comforting and packed with vegetables without feeling like you’re eating a bowl of vegetables.
The blended sauce makes this particularly useful if you’re cooking for someone who isn’t keen on obvious vegetables, or simply want an easy way to add more vegetables into a comforting pasta dinner.
And honestly, once everything is blended, it just tastes like a really lovely creamy pasta sauce.
Final Thoughts
This is one of those recipes where the vegetables are doing all the hard work in the background.
You get a creamy, comforting pasta dinner while sneaking in onion, celery, cabbage and courgette and unless you know they’re there, you probably wouldn’t guess!
It’s a little more effort than opening a jar of pasta sauce, but the homemade result is absolutely worth it.
