To family get togethers I usually make a semi-authentic to the time succotash that goes really well. Even non-veggie eaters usually enjoy it because of the mix and balance of flavours. And it's pretty easy to make either using a frying pan and Crockpot or nowadays just cooking everything in an instant pot by cooking the bacon first on the sautee setting.
And you can scale it up or down as needed depending on the size of the group.
The first step is to render bacon either in a frying pan or in the Instant Pot on sautee. If you're doing a small portion for a family of four just four slices of bacon is needed. You want to cook the bacon to extra crispy (I don’t mean burnt, I mean cook it on medium heat turning occasionally and taking it to dark brown where there’s no floppy bits) to render as much fat as possible. Then set aside the cooked bacon to crumble and add back in (or eat half yourself as the cook, that’s what I usually do).
Once the bacon is removed, leave the fat in the frying pan or instant pot and then add in diced sweet or white onion (for four people just a half will do, for larger amounts scale up) and the same amount of bell pepper (for large batches I typically do different colors to add variety). Cook on medium heat (or sauté on the instant pot) until the onions are carmelized. And by carmelized I mean a light tan color, neither dark brown like you want for French onion soup or Onion dip or just translucent. A minute or so before the onions and peppers are done, add minced garlic at your preferred level (Id start with a heaping teaspoon per every four people but I love garlic).
Once the onions, garlic and peppers are done, that’s when you transfer things to the crockpot (or leave it in the instant pot). To the bacon grease cooked onions, garlic and peppers, you want to add equal portions of :
1) corn kernels - I try to do half white and half yellow sweet corn. I seldom take them from fresh cobs, I usually end up using frozen or canned
2) beans - which means either all baby limas (the small green “butter beans”) or a mix of 1/2 baby Limas, 1/4 green beans, and 1/4 either great northern white beans, navy beans, cranberry beans, or pinto beans. When I do large batches I like to add a wide variety of beans to the final fourth of the makeup. Regardless, make sure everything beyond the green beans have been cooked at least once so either use frozen, canned or rehydrate them and cook them for at least an hour if you use dried beans
3) Fall Squash - my favorite is the turban as it’s pretty close in flavor to the harder to get Native American varieties, but any sweet and buttery fall squash will work such as butternut, delicata, sugar pumpkins, kabucha, red kuri, peanut pumpkin (close second to the turban in my opinion), cushaw, or buen gusto de horno (looks disgusting like the peanut pumpkin but tastes fantastic). Do NOT use spaghetti or acorn squash. You will need to remove the seeds (which can be roasted and eaten out of hand), skin them and cut them into smaller end of your thumb sized chunks.
Add the corn, squash and beans to the instant pot/crockpot and then cook on low for about an hour. Before forgetting about it for an hour, Toss in some fresh ground black or mixed peppercorn and some fresh or dry thyme, tarragon, sage, mint, bay leaf (leave whole to remove later) and the tiniest bit of ground allspice (all of these were native to the time). And the “secret ingredient” which takes the place of historical fermented deer fat and fermented fish to provide the umami seasoning is either a half teaspoon of Vegemite or marmite or a full tablespoon of a quality fish sauce like Mikuni, Golden Boy or Red Boat. Obviously upscale the secret umami ingredient if you’re serving more than four.
After an hour add enough heavy cream that can touch all of the ingredients. You don’t want to go crazy and make a chowder but you want the cream to smooth out all of the flavors and make a “sauce”. Cook for another ten mins on low and then taste. Add any extra salt it may need at this point.
Then you’re done until mealtime. You can make it up to two days in advance so you’re not scrambling on thanksgiving. Then right before the meal, turn the crockpot or instant pot on low and reheat it for 20-30 mins to kill any bacteria that may have grown in the fridge and to get it hot for everyone.
