Vegetarian Fajita Pasta Bake

This fajita pasta bake is packed full of peppers, mushrooms and onions in a spicy sauce topped with lots of cheese! Veggies combined with my favourite fajita seasonings give this pasta bake a delicious twist. 

Pasta bakes are my favourite kind of comfort food! I make them a lot so they need to be really good! We have a few favourites that I make on a regular basis like this Broccoli Pasta Bake or my Pesto Pasta Bake. However, this fajita pasta bake is the one I make the most.

This dish is easy to make and really delivers on flavour. The veggies are cooked in fajita spices with tomatoes. Tossed with pasta then sour cream is added to give a creamy sauce that all good pasta bakes need! Topped with two types of cheese, and cooked until golden brown. Let's get stuck in!

Here's What You'll Need

• Pasta - use pasta that is tubular or has ridges. Penne, rigatoni or fusilli work best. You can use wholewheat or gluten-free pasta if you wish.
• Sour Cream - full-fat is best but you can use half-fat if you want.
• Cheese - I use a mix of mature (sharp) cheddar cheese and Edam cheese for the topping. We love the salty nutty flavour it brings to this pasta bake. You can just use cheddar if you want.

How To Make It

This is just a quick visual guide please see the recipe card below for full instructions and ingredient list.

1. Cook the onion until soft. Add the garlic and cook for a minute, then add the peppers and mushrooms. Cook for a minute or two. 

2. Add the seasonings and stir well. Cook for a minute or two then pour in the tomatoes and tomato puree. Stir well and cook for about 10 minutes. Cook the pasta according to the packet instructions. 

3. Drain the pasta then tip it into a large casserole dish. Add the vegetable mixture and the sour cream and mix well.

3. Add the grated cheese to the top of the pasta then bake in the oven for 20 - 30 minutes. Leave to cool slightly before serving.

Recipe Tips

• Undercook the pasta - when I make pasta bakes I always undercook the pasta slightly. The pasta will cook in the sauce in the oven so undercooking it will prevent the pasta from turning into limp mushy pasta. 2 to 3 minutes less than the packet says should do the trick.
• Save some pasta water - if you find your sauce too thick add some of the pasta water to it to loosen it up a bit. This will also help the sauce stick to the pasta.
• Let the pasta bake rest - leaving the pasta bake to cool off for 5 to 10 minutes will not only leave it to cool slightly saving your mouth but will also give the sauce the chance to settle into the ridges and hollows of the pasta. If you go in too early the sauce will pool around at the bottom of the dish and the sauce will seem thin.
• Add-ins - there is a lot you can do with this pasta bake, try adding in some canned sweetcorn, or roasted courgettes (zucchini). You could also stir some spinach through this too if you want.

This is a great budget-friendly dish, it's perfect for a tasty weeknight dinner. We love this on its own or with a green salad and some garlic bread. If I'm really in need of some extra comfort food I'll serve some crispy potato wedges on the side, the oven is on anyway, and sometimes you need those double carbs, right?
