Why I Grow Thelma Sanders Acorn Squash for My Farm to Table Kitchen

I was gifted Thelma Sanders seeds 5 years ago. The first time I grew it, I had a small garden, so of course I put up a trellis. It was beautiful! The creamy colored squash and the big yellow flowers. Then, when I harvested it and tasted took my first bite, HEAVEN! I was really surprised by the slightly sweet flavor, and I literally ate it off the pan.

On a personal note, growing our own food was not always front and center, but it took on a deeper meaning when my husband was diagnosed with cancer. We started paying closer attention to what we were eating — not in an obsessive way, but in a quiet, intentional way. More whole foods. Less processed. More color on the plate. More knowing exactly where things came from and what was done to them before they got to our table.

Thelma Sanders fit right into that shift. It’s dense with vitamins A and C, high in fiber, and naturally sweet enough that it doesn’t need a lot of added sugar (we watch our sugars now) to taste like a treat. It stores well through winter, which means we have something genuinely nourishing on hand for months after harvest. And I grew it myself from seed — so I know exactly what went into it.

That’s really the whole story of why this squash has a permanent place in our garden.

If you want to grow your own Thelma Sanders, here’s how I grew them vertically on a cattle panel arch on our Kentucky homestead.

Halved and Roasted Thelma Sanders Squash: A Quick Win

I have a vegan daughter-in-law, and I needed something to make her still part of the family dinner gathering. Thelma Sanders Baked Squash is unlike standard acorn squash. Thelma Sanders has a naturally sweet, almost sweet-potato-like flavor that means you need less added sweetener than most recipes call for.

I was able to pop these in the oven and have them ready in no time. She was able to add her favorite things like rice, fresh thyme, cranberries, a drizzle of olive oil, and mix it up inside the halved squash for a perfect dish.

How to Cut Thelma Sanders Acorn Squash

Thelma Sanders has a rounder, more heart-shaped profile than a standard acorn squash, which can make first-timers a little nervous about cutting it. Here’s what actually works:

Place the large flat end down on your cutting board for stability — this keeps it from rolling. Starting at the pointed tip, press your knife firmly straight down through the stem end in one smooth motion. Don’t saw back and forth, one deliberate downward cut is safer and cleaner.

If the squash feels too hard to cut safely, don’t force it. Microwave it whole for 30 seconds first — just enough to soften the skin slightly without cooking the flesh inside.

Use a large spoon to scoop out the seeds and stringy bits. Don’t throw those seeds away — rinse them, toss with olive oil and salt, and roast them at 300°F for 20 minutes for a snack that tastes better than anything from a bag. But really, I feed mine to the chickens!

How to Prepare Thelma Sanders Squash for Roasting

This is where a lot of roasted squash recipes go wrong — and where Thelma Sanders really benefits from one specific technique.

Brush both the cut side AND the skin side generously with olive oil or avocado oil. Both sides. I use avocado oil when I have it because the higher smoke point handles oven heat well, but good olive oil works perfectly too.

Then place the squash cut side DOWN on your lined baking sheet. This is the most important step in the whole recipe. Face-down traps the steam inside as it roasts, keeping the flesh moist and tender all the way through. I learned this the hard way — the first time I roasted them face-up the tops dried out and had almost a fruit leather texture. Not what you want.

Slide the pan into a preheated 375°F oven. Set a timer for 30 minutes and check doneness by piercing the skin with a fork — it should go through easily with no resistance. Depending on the size of your squash, it may need up to 45 minutes. Thelma Sanders tends to run larger than standard acorn squash so don’t rush it.

When they come out, flip them cut side up. You’ll see the edges have started to caramelize, and the flesh is a deep golden orange. That color is your sign they’re done right. Add a pat of butter, salt, and pepper to taste, and your choice of toppings — or eat them exactly as they are. Both are correct answers

Ingredients for Baked Thelma Sanders Acorn Squash

This is really simple, but you can add to it. Start with the basics:

• 1 or 2 Thelma Sanders acorn squash (one half per person)
• 2 tablespoons olive oil or avocado oil
• Butter for finishing, salt and pepper to taste
• I topped mine with cinnamon, butter, and pepita seeds.

What to Put on Roasted Thelma Sanders Squash

Because Thelma Sanders has a naturally sweet, almost sweet-potato-like flavor, it needs less added sweetness than most acorn squash recipes call for. It’s delicious with just butter and salt straight from the oven — that’s my personal favorite, especially reheated the next morning for breakfast.

But it’s also a genuinely versatile base for toppings, depending on who you’re feeding. Here’s what gets served at our table:

Simple and classic: Butter, salt, and pepper. Nothing more needed. This is also naturally vegan if you swap butter for olive oil.

Sweet: Brown sugar and butter — my son’s favorite. A drizzle of maple syrup and a pinch of cinnamon works beautifully too.

Savory and hearty: Ground sausage with tarragon and brown rice mixed right into the squash cavity makes it a full meal. This is how I turn leftover baked squash into dinner.

Vegan and creative: My daughter-in-law’s combination — olive oil, fresh thyme, pepita seeds, cinnamon, cardamom, and a small sprinkle of brown sugar. Mixed inside the halved squash, it’s genuinely one of the best things on our Thanksgiving table.
