If you are in the process of building an investment portfolio, then having a few ASX 200 blue chip shares in there could be a good starting point.

But which blue chip shares could be buys?

Let's take a look at four quality options that analysts currently rate as buys. They are as follows:

Brambles Limited (ASX: BXB)

Brambles could be an ASX 200 blue chip share to buy according to analysts. It is a supply chain solutions company that manages the world's largest pool of reusable pallets, crates, and containers.

The team at Ord Minnett is bullish on the company. It believes that Brambles is well-placed for growth due partly to its Serialisation Plus plan, which is aiming to make its operations more efficient.

The broker currently has a buy rating and $20.60 price target on Brambles' shares.

Flight Centre Travel Group Ltd (ASX: FLT)

Another ASX 200 blue chip share that could be a buy is Flight Centre.

It is the travel company operating the iconic Flight Centre brand, as well as the Aunt Betty, Corporate Traveller, FCM, Stage & Screen, and Travel Associates brands.

Macquarie is a fan of the company and believes that its shares are undervalued following recent weakness. Especially given its belief that things will get easier for Flight Centre as FY 2025 progresses following a soft start.

The broker has an outperform rating and $22.34 price target on its shares.

Goodman Group (ASX: GMG)

A third ASX 200 blue chip share that analysts are tipping as a buy is Goodman Group.

It is a leading integrated commercial and industrial property company. Goodman owns, develops, and manages high-quality, sustainable properties that are close to consumers and provide essential infrastructure for the digital economy. It also has growing and meaningful exposure to the booming data centre market.

The team at Morgan Stanley is bullish on the company and continues to forecast solid earnings growth in the coming years.

The broker has an overweight rating and $42.40 price target on its shares.

Treasury Wine Estates Ltd (ASX: TWE)

A final ASX 200 blue chip share that could be a top buy according to analysts is Treasury Wine.

It is a leading wine company that owns a portfolio of popular brands. This includes the Penfolds, Wolf Blass, Lindeman's, DAOU Vineyards, and 19 Crimes brands.

The team at Morgans thinks the market is undervaluing its shares at present. Especially given the potential of its recent acquisition of DAOU Vineyards. It notes that the "acquisition is in line with TWE's premiumisation and growth strategy and will strengthen a key gap in Treasury Americas (TA) portfolio" and that "if TWE delivers on its investment case, there is material upside to our valuation."

Morgans currently has an add rating and $14.80 price target on its shares.
