This bubbly white bean tomato cheese bake turns everyday cupboard items into a hot, cozy meal ready in just 20 minutes. Mixing smooth beans, zesty tomatoes, and melted cheese makes a dish that's down-to-earth yet filling without spending ages in the kitchen.
I came up with this dish during a super hectic week when I needed something hearty but fast. Now it's my favorite comfort food when I'm craving homemade taste without hanging out by the stove all evening.
Ingredients
- Extra virgin olive oil: Adds a bold, peppery flavor that makes basic ingredients taste fancy
- Thinly sliced garlic: Makes a fragrant base - grab plump cloves with snug skin
- San Marzano peeled tomatoes: They're sweeter and have fewer seeds than regular canned tomatoes
- Fresh baby spinach: Gives color, nutrients and gentle bitterness against the rich cheese
- Cannellini white beans: Add creamy feel and protein - try to get low-salt canned ones
- Italian seasoning: Packs herby punch without emptying your spice rack
- Crushed red pepper flakes: Bring gentle heat - put more or less based on what you like
- Kosher salt: Lifts all the flavors - kosher works better than table salt for taste control
- Mozzarella cheese: Makes that stretchy golden top layer - whole milk kinds melt best
Step-by-Step Instructions
- Get Your Oven Hot:
- First, turn your oven to 475 degrees. This super high heat makes sure you get that awesome golden cheese top without cooking the veggies and beans too much underneath.
- Start The Flavor Magic:
- Warm up a quarter cup of olive oil in your oven-safe pan over medium-high heat until it looks shiny. Toss in your sliced garlic and keep an eye on it until the edges turn golden, about a minute. The garlic makes the oil taste amazing, but watch it closely so it doesn't burn and taste bitter.
- Make Your Quick Sauce:
- Pour in the San Marzano tomatoes carefully so the hot oil doesn't splash you. Smash them up with a potato masher or wooden spoon into chunky bits. Let everything bubble for about a minute, keeping the heat just right so the garlic stays safe. The tomatoes will get juicy and more flavorful.
- Mix In The Good Stuff:
- Drop in your fresh spinach and let it shrink down into the sauce. Add the drained cannellini beans and let them warm up and soak in all the sauce flavors. Sprinkle the Italian seasoning, red pepper flakes, salt, and some black pepper. Stir everything gently so you don't squish the beans.
- Add The Cheese Layer:
- Spread the mozzarella all over the top, making sure to cover everything. The cheese works like a lid that keeps moisture and heat in, helping cook everything underneath just right.
- Bake Until Amazing:
- Put your pan in the hot oven and bake for 8 to 10 minutes until the cheese gets all melty with some golden spots. For extra browning, switch to broil for the last 2 minutes, but don't take your eyes off it or it might burn.
- Dig In Right Away:
- Take it out of the oven and wait just 1 minute before serving. This dish is at its absolute best when the cheese is still bubbling and stretchy. Serve with tortilla chips for scooping or crusty bread for soaking up the sauce.

San Marzano tomatoes are the hidden hero in this dish. Their sweet rich flavor and meaty chunks make a sauce that tastes like it cooked forever instead of minutes. I learned about them during a cooking lesson in Italy, and they completely changed how I make quick tomato sauces.
Make It Your Own
This dish is super flexible based on what's in your kitchen. Try great northern beans or chickpeas instead of cannellini. Switch spinach for kale or arugula for different tastes. When you've got them, fresh herbs like basil, oregano, and thyme can replace the Italian seasoning. Think of this recipe as a starting point that works with whatever you've got on hand.
Historical Context
This meal has roots in Italian country cooking, where simple, filling ingredients made satisfying dinners. Beans and tomatoes have been paired throughout the Mediterranean for hundreds of years, with cheese added as a special treat when families could afford it. What started as necessity cooking has become beloved comfort food that's way more popular than its simple beginnings suggest.
Serving Suggestions
Though it's great by itself with tortilla chips, this bake can be the star of a full meal. Pair it with a simple green salad with lemon and olive oil dressing for a light dinner. If you're hungrier, add some crusty bread and roasted veggies on the side. It also works as a fancy side dish with grilled meat or can be spooned over pasta for a complete dinner.

Best when it's hot from the oven and don't be afraid to try adding your own favorite ingredients!
Frequently Asked Questions
- → Can I swap the beans out?
For sure! Navy beans or Great Northern beans are great swaps for cannellini. Chickpeas work too, though they'll add a firmer bite and earthy flavor.
- → What if I don’t have San Marzano tomatoes?
Feel free to use regular canned whole tomatoes, though San Marzano gives a sweeter taste. Diced or even halved cherry tomatoes are okay too for a chunkier texture.
- → How can I make it spicier?
Easy! Add more red pepper flakes, fresh chopped chili, or a splash of hot sauce to the mixture. A bit of cayenne can also give it a kick.
- → Can I prep this ahead of time?
It’s best fresh from the oven with bubbling cheese, but you can prep the beans and tomatoes early. Just chill the mix, add cheese later, and bake when ready to serve.
- → What goes well with this besides chips?
Grab some crusty bread, serve over pasta or rice, or pair it with a fresh salad. For a lower carb idea, use veggie sticks or roasted veggies on the side.
- → Can I throw some meat in?
Of course! Toss in cooked sausage, shredded chicken, or crispy pancetta before baking. These work great if you want a heartier option.
