Easy Cheesy Polenta with Tomatoes & Butter Beans: A 30-Minute Vegetarian Dinner

If you’re searching for easy recipes UK cooks can rely on after work, this cosy polenta bowl is a strong answer to what to cook tonight. It’s warm, filling, budget-friendly, and built from simple supermarket ingredients you may already have in the cupboard. Best of all, it follows a true cook once, eat twice approach, so you can make dinner tonight and set yourself up for an even quicker meal tomorrow.

Polenta is one of those ingredients that often gets overlooked in favour of pasta, rice or noodles, yet it’s perfectly suited to quick meals. Quick-cook polenta comes together fast, gives you a creamy base in minutes, and pairs beautifully with store-cupboard staples like tomatoes, beans, garlic and cheese. For home cooks looking for vegetarian dinner recipes that feel comforting without requiring much effort, this one ticks a lot of boxes.

This dish also fits neatly into modern weeknight dinner ideas: it’s meat-free, satisfying, and flexible enough to adapt to what’s in the fridge. The tomato and butter bean topping adds protein and fibre, while pesto and toasted pine nuts bring a fresh, restaurant-style finish without making the meal complicated. It’s the kind of recipe that feels a little special, but stays firmly in the realm of easy dinner recipes.

• 1½ tbsp olive oil
• 2 garlic cloves, peeled and grated
• 250g cherry tomatoes, halved
• 1 x 570g jar butter beans, drained and rinsed
• 400ml vegetable stock
• 100g quick-cook polenta
• 40g parmesan, grated
• Flaky sea salt, to taste
• Juice of ½ lemon
• Fresh basil pesto, shop-bought or homemade, to serve
• 1 handful toasted pine nuts, to serve

1. Set a large frying pan over a low heat and add the olive oil. Stir in the grated garlic and fry gently for one minute, just until fragrant.
2. Add the cherry tomatoes, increase the heat to medium, and cook for around five minutes, stirring occasionally, until they begin to soften and release their juices.
3. Stir in the butter beans, cover the pan, and cook for another five minutes so they warm through and soak up the tomato flavour.
4. Turn off the heat, give the mixture a final stir, and keep it covered while you make the polenta.
5. Pour the vegetable stock into a large saucepan and bring it to the boil. Whisk in the quick-cook polenta, gradually and steadily, so it doesn’t clump.
6. Whisk vigorously for about one and a half minutes, until the polenta thickens and becomes smooth and glossy.
7. Take the pan off the heat, then stir in the parmesan, a little flaky sea salt, and the lemon juice. The texture should be loose and flowing; if it looks too stiff, add a splash more stock to loosen it.
8. Taste and adjust the seasoning if needed.
9. Spoon the polenta into wide bowls, pile the tomato and butter bean mixture on top, then finish with pesto and toasted pine nuts.

When you’re planning budget recipes UK households can repeat without boredom, a meal like this makes a lot of sense. Polenta is inexpensive, especially compared with many convenience foods or meat-based mains, and the rest of the ingredients are mostly pantry-friendly. Tinned or jarred beans, garlic, stock, cheese and tomatoes are all practical purchases that stretch well across multiple recipes.

It’s also a smart choice for anyone trying to build a week of family meal ideas around low-cost, flexible components. The ingredients are easy to scale up, and the recipe feels substantial enough for adults while still being approachable for younger eaters. If your family enjoys creamy pasta, risotto or mash, polenta can be a welcome change that still delivers the same comfort-food feeling.

For households trying to eat more plants, this dish offers a good balance of protein, carbs and vegetables. That makes it useful as part of a rotation of cheap family dinners, especially when you want something filling but not heavy.

One of the most useful things about this recipe is that polenta transforms beautifully after cooking. The source idea behind the dish is simple but clever: make a batch, enjoy half as a soft, creamy dinner, then save the rest for another meal the next day.

To do that, pour any leftover polenta into a lightly oiled tray and let it cool. Once chilled, it will firm up into a sliceable block. You can cut it into squares, rectangles or even chips, then fry or oven-bake until crisp. This turns one quick dinner into a second meal with almost no extra effort.

That kind of planning is ideal for people building meal prep ideas into their week. It also works well if you’re trying to reduce food waste or keep weekday cooking manageable. Instead of starting from scratch each night, you get a ready-made base that can be repurposed into a second lunch or dinner.

• Crispy polenta chips: cut into batons, fry until golden, and serve with extra pesto or a tomato dip.
• Polenta squares with roasted veg: pan-fry the slices and top with leftover vegetables or salad.
• Cheesy polenta toast-style bites: reheat the slices and top with more parmesan and a spoonful of the bean mixture.
• Simple lunch bowl: serve crisped polenta with wilted greens, an egg, or extra beans for an easy midday meal.

Good simple dinner ideas are usually flexible, and this recipe is no exception. If you don’t have exactly the same ingredients, there are plenty of easy swaps you can make.

• Quick-cook polenta: use the dry coarse type, not the ready-made vacuum-packed blocks. If you only have standard polenta, expect a longer cooking time and follow the packet instructions.
• Butter beans: cannellini beans or chickpeas also work well. Butter beans give the sauce a soft, creamy texture, but the recipe is forgiving.
• Parmesan: use a vegetarian hard cheese if needed, or a similar aged cheese with a salty finish.
• Pesto: shop-bought pesto is perfectly fine. If you have basil, pine nuts and oil, homemade pesto is a nice upgrade.
• Pine nuts: toasted sunflower seeds or chopped walnuts are a useful alternative if pine nuts are pricey.

If you’re catering for different diets, you can also adapt this recipe easily. Use a vegetarian-friendly cheese, check the pesto label if needed, and make sure your stock is suitable. That makes it a handy option for mixed households looking for easy recipes UK families can share.

Polenta can go from silky to stiff quite quickly, so the key is to keep it loose enough to spoon. The ideal consistency is often described as “flowing like lava,” which is a useful benchmark. If the mixture seems too thick before serving, add a splash more hot stock and stir well.

Whisking is also important. Adding the polenta gradually while whisking helps prevent lumps and gives you a smooth result. Once the cheese goes in, taste again before serving. Parmesan brings saltiness, so you may need less salt than you expect. A little lemon juice at the end brightens the whole dish and stops it tasting overly rich.

For the topping, don’t rush the tomatoes. Let them soften gently so they break down into a light sauce rather than staying raw. The butter beans should be heated through and tender, not cooked to the point of falling apart. That contrast between creamy polenta and soft tomato beans is what makes the dish so satisfying.

Serve this recipe in wide shallow bowls so the polenta can act as a soft base for the topping. Finish with pesto in small spoonfuls rather than mixing it all in; that gives bursts of basil flavour and keeps the dish visually appealing. A sprinkle of toasted pine nuts adds crunch, while a little extra parmesan makes it feel complete.

If you want to turn it into a fuller spread, serve with a simple green salad, some steamed greens, or a piece of crusty bread. For a more substantial family dinner, it also pairs well with roasted courgettes, peppers or mushrooms. These add-ons can help stretch the meal without much extra work.

Recipes like this are exactly why polenta deserves a place in the UK home cook’s cupboard. It’s fast, inexpensive and surprisingly versatile, which makes it ideal for anyone who wants quick dinner ideas that don’t feel repetitive. If your usual rotation leans heavily on pasta bakes, stir-fries and traybakes, this creamy vegetarian dinner is a welcome change of pace.
