The ingredients for this red pepper pasta will give you a delicious and very easy to make vegetarian dinner to enjoy! The main ingredients you will need are:
- Red bell peppers: the main ingredient, these are used as a swap for tomatoes. Make sure they are fresh without any bruising or dents.
- White onion and garlic: the traditional flavourful base of pasta sauces. Up the amount of garlic if you are a fan!

Step by step instructions
Just a few simple steps to make this pasta dish:
Dice the bell peppers into large pieces and place on a lined baking tray. Drizzle with oil and sprinkle with a little thyme. Roast for approximately 30 minutes until they are tender (image 1). If the skins have blackened, it is best to wait for them to cool a little then remove the skin.
While the peppers are roasting, fry the onion and garlic until softened (image 2).
Cook your pasta according to packet instructions, reserving a little of the pasta water.
While the pasta is cooking, add the roasted peppers, onion, garlic, basil (leave a few leaves aside for garnish), ricotta cheese and a pinch of salt to a food processor or blender (image 3). Blend until it becomes a creamy sauce (image 4). If it is too thick, add a splash of the reserved pasta water and blend again.
Drain your spaghetti, and return it to the pan. Stir through the sauce, and re-heat slightly if necessary. Add a grind of black pepper to preference (image 5).
- Use good quality ingredients. The sauce has fairly gentle flavours, so you want to have the freshest basil and cheese to elevate the taste!
- Adjust the consistency of the sauce with a little of the reserved pasta water if required.
- You can use most forms of pasta, it doesn't have to be spaghetti. Gluten free pasta alternatives are also good.
Frequently asked questions
You can use cottage cheese instead. It will alter the flavour a little but still be delicious.
It is personal choice whether you peel bell peppers or not after roasting them. It isn't really necessary if they are being blended into a sauce unless the skins have blackened, in which case it is best to peel them.
I would suggest that roasting the bell peppers yourself gives them more flavour and is more fresh than using a jar. My low histamine readers would likely be better using peppers they roasted themselves.
