Side Dishes
This Buckeye Beans recipe transforms simple ingredients into a Southern classic that feels like a hug in a bowl—crispy fried onion crowns perched over creamy mushroom and bean medley.
I first tasted this dish at a diner in Ohio, where the owner swore by her "secret" baking method, and I've been perfecting it ever since.
The key lies in balancing textures: tender baked beans with a velvety mushroom base, crowned with onions that turn golden and crispy in the oven.
The beauty of Buckeye Beans is their versatility—traditional recipes rely on bacon and brown sugar for depth, but modern adaptations use smoked paprika or vegan bacon to keep it inclusive. I've tested this recipe in both my cramped Boston apartment and a friend's farmhouse kitchen, and it delivers every time.
The onions develop that signature crispness only when baked just right, while the bean mixture stays creamy without turning mushy.
What you'll end up with is a dish that's rich, comforting, and impossible to resist—perfect for game day, potlucks, or a cozy weeknight dinner. The aroma alone fills the kitchen with warmth, and the contrast of crispy onions against the creamy base makes each bite satisfying.
This recipe is a testament to how simple ingredients can create something extraordinary when prepared with care.
Whether you stick to the classic version or experiment with modern twists, the result is always a crowd-pleaser. Let's get started on this Southern staple that's as much about tradition as it is about flavor.

| Butter 🧈 | 4 tbsp | Unsalted, for sautéing |
| All-Purpose Flour 🌾 | ½ cup | For thickening sauce |
| Whole Milk 🥛 | ½ cup | Full-fat for creaminess |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |

The bacon and onions are the stars here. Thick-cut bacon from Costco or your local butcher gives the best texture, but regular supermarket bacon works in a pinch. Look for onions with vibrant color and no bruising—they should hold their shape during baking. The mushrooms should be firm, not slimy, and cremini or white varieties work best for that meaty texture. If you're using dried beans, soak them overnight—this cuts the cooking time dramatically and ensures they stay tender. For the brown sugar, light or dark both work, but light has a slightly cleaner finish.
No bacon? Smoked turkey bacon or vegan bacon works just as well. The ketchup and tomato paste can be swapped for tomato sauce if you prefer, but the paste gives a deeper flavor. Running short on mushrooms? Substitute with cremini or portobello mushrooms for extra richness. The smoked paprika is optional but adds that classic Southern depth—Penzeys or McCormick are solid brands. If you're making this ahead, cook the beans and sauce first, then assemble with the onions just before baking to keep them crispy.
Store the cooked beans and sauce in an airtight container for up to 5 days in the fridge. The onions need to be baked fresh for that signature crispness, so don't prep them too early. For leftovers, the onions can be reheated in the oven at 350°F for 5-10 minutes to restore their crunch. Freeze the bean mixture without the onions for up to 3 months—just add the onions fresh when reheating.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe when I’m too tired to wash dishes. Toss everything—beans, onions, bacon, sugar, and ketchup—into one pot, simmer, and let it meld. No chopping, no fuss, just pure, smoky-sweet satisfaction.
- Sweet-Savory Balance: That brown sugar-ketchup combo? It’s genius. The bacon adds saltiness, the onions caramelize, and the beans soak it all up like a flavor sponge. Honestly, it’s the kind of dish where every bite makes you think, “Wait, why don’t I make this more often?”
- Tailgate or Taco Night: Between us, this is my go-to for game days or when I’m craving something hearty but not heavy. Serve it as a side with cornbread, or—here’s what sold me—crumbled over nachos for a sweet-and-salty twist. Even my picky teens don’t complain.
- Budget-Friendly Leftovers: Navy beans stretch forever, and bacon bits make it feel fancy. I make a big batch on Sundays, and by Thursday, I’m still eating it—straight from the fridge, no reheating drama. Plus, it’s cheaper than takeout, and way tastier.
Step-by-step instructions for buckeye beans
Transform simple ingredients into a rich, textured dish with crispy fried onions and velvety mushroom sauce.
Prepare the Navy Beans for Maximum Tenderness
Place the 1.5 cups of dried navy beans in a large bowl and cover with plenty of cold water by at least 2 inches. Soak overnight or for at least 8 hours - this ensures even cooking and prevents tough texture. Drain and rinse thoroughly before using.
Transfer the soaked beans to a 4-quart pot and cover with fresh cold water by 2 inches again. Add the 1.5 teaspoons of salt and bring to a boil over high heat. Once boiling, reduce to a gentle simmer and cook for 45-60 minutes until the beans are fork-tender but not mushy. Drain and set aside, reserving 1 cup of the cooking liquid for later use.
Create the Creamy Mushroom Base
In a large skillet, cook the 8 ounces of chopped bacon over medium heat until crispy, about 8-10 minutes. Remove the bacon with a slotted spoon and set aside, leaving the rendered fat in the skillet. Add 2 tablespoons of the butter to the bacon fat and melt over medium heat.
Add the 1 pound of sliced mushrooms and cook for 5-7 minutes until they release their moisture and begin to brown. Stir in the 4 cloves of minced garlic and cook for 30 seconds until fragrant. Sprinkle the mushrooms with the 0.5 teaspoon of smoked paprika and stir to combine. Remove from heat and set aside.
Build the Sauce with Rich Flavors
In the same skillet, melt the remaining 2 tablespoons of butter over medium heat. Add the 2 whole yellow onions that have been sliced and cook for 8-10 minutes until golden brown and caramelized. Stir in the 0.25 cup of tomato paste and cook for 2 minutes until it darkens slightly.
Pour in the 0.5 cup of ketchup and the 0.5 cup of brown sugar, stirring to combine. Add the cooked navy beans and reserved bean cooking liquid, along with the 0.5 cup of whole milk. Bring to a gentle simmer and cook for 10 minutes until the sauce thickens slightly. Season with the 0.5 teaspoon of black pepper.
Create the Crispy Fried Onion Crown
In a separate skillet, melt 2 tablespoons of butter over medium heat. Add the remaining sliced yellow onions and cook for 5-7 minutes until they begin to soften. Sprinkle the onions with the 0.5 cup of all-purpose flour and stir to coat evenly. Cook for 3-4 minutes until the flour is golden brown and crispy.
Carefully transfer the crispy onion mixture to a paper towel-lined plate to drain excess fat. Return the onion mixture to the skillet and cook for an additional 2-3 minutes until deeply golden brown and crispy. This is your crowning element that will add texture contrast to the creamy base.
Combine and Serve with Perfect Texture
Return the creamy mushroom and bean mixture to the skillet and stir in the crispy fried onions. Cook for 2-3 minutes until everything is heated through and the onions are evenly distributed. The contrast between the crispy onions and creamy base should be striking.
Divide the buckeye beans among serving dishes, garnishing each portion with the reserved crispy bacon and a sprinkle of the 0.25 teaspoon of ground black pepper. Serve immediately while the onions are still crispy and the sauce maintains its creamy texture. Each bite should deliver the perfect balance of textures and flavors.
Pro Tips For Making Buckeye Beans
- CRISP THE BACON FIRST: Cook the bacon until it’s deep golden, not just pink—this makes all the difference in flavor. I used to rush it, but crispy bacon adds that smoky backbone the beans need. Save the fat for frying onions later (yes, even if you’re impatient like me).
- SOAK BEANS OVERNIGHT: Skip the quick-soak shortcut—give those navy beans a full 8–12 hours in water. I learned this the hard way after my beans turned mushy; soaked properly, they’ll stay tender but hold their shape through the long simmer.
- CARAMELIZE ONIONS LOW AND SLOW: Don’t rush the onions—cook them on medium-low for 15–20 minutes until they’re deep amber, not just soft. The sweetness balances the sugar and ketchup, and burnt bits ruin the whole dish. (Your future self will thank you.)
- STIR IN SUGAR LAST: Add the brown sugar after the beans are mostly tender, not at the start. I was skeptical until I tried it—this keeps the beans from turning gluey and lets the sugar melt into a glossy, caramelized finish.
Storing and reheating this recipe
Refrigerator Storage
Store the cooked bean mixture in an airtight container for up to 5 days—I use glass Pyrex with snap-on lids to keep flavors fresh. The onions should be baked fresh before serving, so don’t prep them ahead.
If you must store them separately, keep the onions in a sealed bag and bake at 350°F for 5-10 minutes to restore crispness. The sauce thickens further overnight, so you might need a splash of water or milk when reheating. ❄️
Freezer Prep
Freeze the bean mixture (without onions) in quart-sized freezer bags for up to 3 months. Leave 1 inch of headspace for expansion and squeeze out excess air to prevent freezer burn.
Label with the date—trust me, you’ll forget! When reheating, add the onions fresh after baking to maintain their crispy texture. Thaw overnight in the fridge for best results. ❄️
Oven Reheating
For the best texture, reheat the bean mixture in a skillet over medium heat with 2 tablespoons of water or milk to prevent drying. Cover and simmer for 5-7 minutes until warmed through.
If using leftover onions, bake them at 350°F for 5-10 minutes on a parchment-lined tray until golden and crispy again. The oven method works well for larger batches. 🔥
Microwave Shortcut
For quick reheating, transfer a portion to a microwave-safe bowl, cover loosely, and heat on 50% power for 2-3 minutes. Stir, then continue in 30-second intervals until reaching 165°F.
Add a splash of water or milk if it looks dry. Skip the microwave for the onions—they’ll turn soggy. 💡
Make-Ahead Tips
Prep the bean mixture 2 days ahead and store in the fridge. The onions can be sliced and coated in flour the night before, then baked fresh when ready to serve.
I often make a double batch—one for dinner and one for lunches. The flavors deepen over time, making it even more comforting. 📅
Serving Fresh
Serve immediately after combining the crispy onions with the bean mixture to keep that perfect texture contrast. Garnish with extra bacon and a sprinkle of black pepper right before eating. The aroma alone will have everyone rushing to the table—trust me, it’s worth the wait! 🍽️

Frequently asked questions
What makes Buckeye Beans different from regular baked beans?
Buckeye Beans stand out with their crispy fried onion crowns baked right into the creamy bean mixture. Unlike traditional baked beans, this recipe layers textures with tender navy beans, rich mushroom sauce, and golden onions that stay crunchy. The addition of bacon and brown sugar gives it a deeper, slightly sweet-savory flavor profile.
Can I substitute navy beans with another type?
Yes, but navy beans are ideal for their firm texture. Great alternatives include great northern beans or kidney beans. Avoid pinto beans—they get too soft. Always soak dried beans overnight for best results.
How do I keep the onions crispy when reheating leftovers?
Never microwave the onions—they'll turn soggy! For leftovers, bake them fresh at 350°F for 5-10 minutes on a parchment-lined tray until golden again. Store onions separately in an airtight bag if prepping ahead. The secret is reheating them just before serving.
Is there a vegetarian version of this recipe?
Swap bacon for smoked paprika or vegan bacon bits, and use vegetable broth instead of milk. The mushrooms add enough umami depth to keep it satisfying. The crispy onions remain the star of the show.
Why did my onions turn out mushy instead of crispy?
Overcooking is the most common mistake. Cook onions only until golden brown (about 3-4 minutes after adding flour), then bake them fresh before serving. Also ensure you're using all-purpose flour for coating—not cake flour.
